Digital Camera Memory - An Introduction


Digital Camera Memory - An Introduction

 by: Jakob Jelling

The digital camera is essentially a computer-based device, whose core is controlled by the computer. And as a result the photographs are stored in a location called memory. Now, this concept is or paramount importance in discussing digital camera. Strictly speaking, digital camera memory is where digital pictures are stored inside the camera. The digital camera memory is an essential and often a very neglected and overlooked section of equipments for digital photography and camera. There are many types of memory available for digital cameras, and it is a good practice to mull over what type of memory a camera uses before buying a digital camera. This discussing is aimed in revealing some of this relevant information!

Knowledge of the digital camera memory is very essential for using such a camera and capturing photographs. The most common form of such memory is a memory card. These are reusable, have a limited capacity and can always be installed when required in excess. A person needs to be well informed about enough memory available for taking photographs. And accordingly make arrangements. Generally, digital cameras come available with low capacity memory cards, and it is a wise purchase to acquire higher capacity memory cards in order to budget for an additional card for later use.

With the increment of a camera mega pixel counts, it becomes essential to use higher capacity memory cards. Some of the small sized cards are for example the 64 megabyte cards and larger ones are like 1-gigabyte cards or combinations of megabyte cards.

Digital camera memory is available in many shapes and facade depending on the type of digital camera that is being used and even and the number of pictures that are required to be stored in the digital camera memory. These different types of memory are solely dependant upon the requirements of the digital camera, like for example a camera using compact flash type 1, requires the use of compact flash type 1 digital camera memory. Other examples of types of digital camera memory are Compact Flash Digital Camera Memory. It is suitable for rugged and rough handling and is also resilient for incessant usage. This is also small in size to assist better handling and flexibility. What more, it is cheap and anyone can afford it!

Generally, the sizes of a digital camera memory are as follows, 64 MB, 128 MB, 256 MB, 512 MB, and 1 GIG. Again, the digital camera memory depends upon the file format used to store photographs upon and the compression used by the manufacturer when storing digital images into memory.

Coming to the concluding portion, it is recommended to get hold of one 256 megabyte or two 128 megabyte cards for a 3-5 mega pixel compact digital camera. For higher resolution photographs, 512 megabyte and 1 gigabyte cards are also available. These are some of the guidelines for revealing the true facts about the different digital camera memories and their secrets. Summing up in a few words, with such a powerful tool as the digital camera, a proper selection of memory can help a person achieve the glorious tasks of freezing a precious moment from life for eternity!

The Confused Photographer's Guide to On-Camera Spotmetering (The Confused Photographer's Guide to . . . Series) (The Confused Photographer's Guide to . . . Series)

The Confused Photographer's Guide to On-Camera Spotmetering (The Confused Photographer's Guide to . . . Series) (The Confused Photographer's Guide to . . . Series)
World's first book written to illustrate the on-camera spot metering technique for 35mm, Digital, and Medium Format photographers:

All types of metering systems used in different cameras (with the exception of the on-camera spotmeter operated by a skilled photographer) use a "cookie-cutter" approach to photographic exposure. What this means is the camera meter measures the various tones of your subject, and then averages all of the tones in order to come up with an overall exposure. Sometimes the overall exposure works and sometimes it doesn't. With this approach, the ball is in the camera's court and in many instances the photographer has no hand in the final look of the image. With on-camera spotmetering, the photographer uses a "tailored" approach to find the correct exposure for a very specific subject. With this approach, the skilled photographer interprets the spotmeter readings from the subject and establishes the correct exposure that captures the desired image (what the eye sees) on film. The consistency and flexibility of the narrow-angled spotmeter makes it the most powerful and versatile exposure tool in existance today. The only catch in using a spotmeter is that the photographer must have the skill to use this powerful tool correctly and effectively. The Confused Photographer's Guide to On-Camera Spotmetering does just that! It is simple, easy-to-follow, and uses a common-sense teaching approach to the material. With more than seventy full-page illustrations, it is designed to get the beginner and the intermediate photographer started in a couple of days. I assume that you have a camera with a built-in spotmetering (partial metering) feature. I also assume that you have a ninth grade education and are willing to learn. To facilitate your learning process, I have included a two page cheat sheets for each of the following cameras: Canon EOS 10D Digital Slr, Canon EOS 20D Digital Slr, Canon EOS 3, Canon EOS A2/A2E, Canon EOS Elan 2E, Canon EOS Elan 7E, Canon EOS Rebel 2000, Canon EOS Rebel Ti/300V, Canon PowerShot G3 Digital, Canon PowerShot G5 Digital, Minolta Maxxum 5, Minolta Maxxum 7, Minolta Maxxum 9, Minolta Maxxum StSi, Nikon CoolPix 990 Digital, Nikon CoolPix 995 Digital, Nikon CoolPix 4500 Digital, Nikon CoolPix 5700 Digital, Nikon Coolpix 5000 Digital, Nikon Coolpix 8700 Digital, Nikon D70 Digital Slr, Nikon F4, Nikon F5, Nikon F100, Nikon N50, Nikon N55, Nikon N60, Nikon N6006, Nikon N65, Nikon N70, Nikon N75, Nikon N80, Nikon N8008s, Nikon N90/N90s, Pentax *ist, Pentax *ist-D Digital SLR, Pentax 645N Medium Format, Pentax MZ-S, Pentax PZ-1P, Pentax ZX-5N, and Sony DSC-F717 Digital. If your camera is not listed here, you will still be able to learn the technique and apply it successfully.

Customer Review: Great Book

Until I had this book one takes photographs that the camera takes. After reading this book you can be in control. The Author gives a very detailed and easy to understand explanation of why some photographs don't turn out the way we expect them to and tells you how to manipulate the new electronic exposure meters built in to today's cameras.



I recommend this book to all budding photographers. That's the only way to pay tribute to this book and author.

Customer Review: One of the best photo buys I ever made....

After reading this book, I feel as though a veil has been lifted. I always wondered why my photos, although looking good, just lacked a certain "something". My camera, a Rebel Ti, does not have spot metering. Now I am able to understand how to do spot metering with a partial metering system.



I never thought about "tonal" quality as it applies to a photograph. Now I can look at the computer generated settings and make the necessary manual adjustments to take tone into account.



Very good purchase.

For Mac fans, iPhoto 6: The Missing Manual has a whole section on digital photography.

Customer Review: Great Book For the Terminology Challenged

I found the book to be comprehensive. It is a great starting point for the novice and a good reference for someone who is familiar with the subject, but not a pro. The chapter headings are "tabbed" in the upper corner of the page, which makes topics easy to find. Also, the numerous illustrations and various fonts made the book extremely readable.

Customer Review: Great book - but for absolute beginners only

Very well written - clear, simple, easy to follow. And it does have some great tips - even for the intermediate photographer. But this is really a book for someone who has never used a digital camera before or who has never taken the time to understand their camera's features. It also spends a lot of space discussing several specific photo management software programs (EasyShare, Picasa, Elements), as well as some common on-line photo sharing sites. If you're new to this art then this book will be a great start. But if you're already familiar with your camera and with digital photo editing and on-line sharing, you probably won't get much new out of this. Plus, if you don't plan on obtaining the specific software the authors discuss, at least half the book will be of no use to you.

Customer Review: Accessible language to beginners !

Teach yourself visually Digital Photography, 3rd edition, might be the book that makes beginners in digital photography jump in the digital technology photo-taking.

I know middle level executives who cling to their film camera because of the learning curve.

There are really TWO PARTS in the book : one on taking the photo and using the camera that takes 113 pages and the second part on processing the photos in the computer that runs from page 114 to page 265.



Here is an idea of the language used : Light and Color on page 26 " All colors within the color spectrum are contained in visible light. The amount of any particular color within the light is determined by its source , and for outdoor light, the time of day. For example, more reddish orange color is seen at sunset when ..."



The book will help you before buying a digital camera and once you have bought such a camera. You can read 2 pages within 15 minutes .



Basic but fundamental.



Customer Review: A great Book to start with

This book is basic in its approach to covering digital photography. But the illustrations make it a fun way to learn. Don't be fooled though, the content is powerfull and concise. Its a great book for beginners and those needing a refresher.

Buying a new digital camera

I feel, after visiting so many websites and reading so much advice, and also by frequently visiting photography forums, that I have to speak on this subject.

I feel, after visiting so many websites and reading so much advice, and also by frequently visiting photography forums, that I have to speak on this subject.

For the majority of the buying public, there are 2 categories that we fall into when getting started or upgrading in digital photography, the "Absolute Beginner" or the "Amateur" (or serious amateur sometimes labelled as semi pro).

Now for the beginner, or someone getting started in photography itself (not just digital), the choice of cameras nowadays is quite overwhelming! Everywhere you look there are cameras, not just in camera shops like the good old days. You even get given a cheap digital camera as a gift for buying something else in some places. There are reasonably powerful digital cameras in the more expensive mobile phones now and they come in all shapes and sizes.

So where do you possibly start and how do you make that choice for buying a camera for yourself or someone else. Really it is quite simple and there are 3 criteria you should look at:

1.Quality - If you want the camera to last at least a few years and not get bothered by a bit of bashing about, go for quality. A titanium body, not plastic, something that is fairly heavy and robust in your hands, you can feel quality!

2.Features - Do you want quality video capabilities? How big do you want to print the pictures that come from the cameras files (how many mega pixels)? Do you want to have at least some manual features so you can get a bit creative? Or do you just want a "Point-and-shoot" digital camera?

3.Price - You will have a budget in mind of how much you want to spend. Get the best camera and memory you can for your budget, worry about extras later! Don't be cheap; if you want reasonably good quality prints, by spending too little on a very cheap camera, you will waste paper, printer ink and/or good money at your local lab. Get a good make and model of digital camera now and it will outlast a cheapie 4 or 5 times.

DO NOT be swayed by digital cameras that have "Non-Photographic" features, gadgets and gizmos. Any of these unnecessary features added means that some quality has been sacrificed elsewhere. Buy a camera to be a camera, and nothing else. I would also suggest buying one of the top brands such as Canon, Nikon, Konica-Minolta, Olympus etc., they may cost a little more, but the difference in quality is worth it. They all make cheaper end cameras too.

Look for decent features such as a good optical zoom, NOT digital zoom. Digital zoom is an unnecessary marketing tool; it is the same as zooming in on the photo once you get it onto your PC. 10-20X digital zoom is acceptable but I have seen video cameras with 1000X digital zoom, have you ever tried holding the camera steady at these kind of magnifications, even with a tripod?!!

Basically, write down exactly what you want and need from the camera, go to a reputable dealer and buy a good branded camera that has what you need for your requirements and budget, don't be swayed by the salesperson into buying more than you need.

Now, the Amateur or Semi Pro. When you start to look at Semi professional Digital SLR's or Advanced digital compact cameras, the choice is a little less but no less confusing. The same advice goes here as in the previous section, think about what you need the camera for, how you think you may progress in this hobby and your budget.

The "prosumer" advanced digital compact cameras available today are steadily encroaching on the quality of the DSLR, although in my opinion, they will never catch them. The optical zooms are fantastic, the sensors, albeit smaller than the DSLR are powerful and produce stunning images, and some even have "built-in" image stabilisersGreat!

Again, my advice would be to go for quality. These cameras are more expensive anyway and you want one that will last and put up with a bit of knocking from your "getting creative in photography" moments! Once you have your advanced digital compact, dont be swayed by the latest upgrades, updates or releases. Get to know what you have, learn how to use it effectively and learn the photography side of photography, not the technical side.

Once you are happy with your progression and feel that you want to move on, be more in control and maybe even start to earn from photography, only then should you splash out and upgrade to a Digital SLR.

The Semi Professional Digital SLR or consumer DSLR is a fantastic thing in photography. Many of the "die-hard" film photographers are seeing the light and going digital. Many aspects of film are still widely used and will do for some time, as large format film photography produces the absolute finest detail I have seen (at the time of writing. In 2020, who knows?).

However, the latest batch of Digital SLR's have now reached the point where they match or out perform 35mm film. It is predicted that next year (2006) will be "boom time" for the sales of DSLR's as the quality increases and the prices come down. There has never been a better or cheaper way to get into 35mm photography!

The BIGGEST thing to consider when buying a DSLR kit is to choose your brand loyalty. Look at Canon, Nikon, Konica-Minolta, Olympus, Kodak etc., and make your choice, why? As you progress and become more enthusiastic or serious, you will want to add more lenses to your kit. Wide angle, telephoto, zoom, macro, standard.there is a massive choice.

With the way technology is going, you are much more likely to upgrade your camera than you are your lenses and it will be a lot cheaper to do so once you really get into this hobby, believe me! One decent lens in my kit cost 2,000 (1400) alone. A decent lens will, with care, last you a lifetime. There is only a certain level of quality of the glass you can obtain with optics so remember this point when buying your camera.

My choice? Canon. I used to work for Nikon and had a preference towards them, but nowadays all my kit is Canon. I feel they are one step ahead with technology and the lenses (especially the nice white ones) are amazing! Just look at the next major sporting event on TV, how many "White" lenses you see. Only Canon makes white lenses.

Again, once you have made your choice, BUY the camera, ENJOY it and LEARN from it! If the sensor (i.e. 8MP of bigger) produces LARGE, high quality prints, why be swayed by the newer, latest upgrades? Photography is about "learning" and enjoyment, DO NOT be intimidated by technological gobbeldy gook, as long as your camera has the features that you need, quality to match and you build a nice set of lenses over time, who cares if the latest model has 0.1% better white balance control, or flashing lights?

If you are new to Digital SLR's, I have a section on my website that explains all the bits and buttons

Digital SLR Newbie?

All the best and enjoy yourselves!

Surveillance Camera Systems: Preserving The Integrity Of Gaming Tables

The better the gambler, the worse the man, wrote Publius Syrus, and all casino owners, from Nevada to Monte Carlo believe him. In fact, they believe him so well that they do not just put watchers and security officers near tables, they put up surveillance camera systems, too.

It is unheard of for casinos not to have surveillance camera systems. After all, fortunes, big or small, are lost and won in the space of seconds inside casinos. With so much money at stake, casino owners and managers therefore anticipate the worst sides of human nature to surface. There will always be people who will try to beat the odds by cheating the house; and what better way to catch these people than through surveillance camera systems? These watchers never sleep, never blink, and never get distracted by a scantily clad woman, for example, or a brawl that erupted in one of the tables.

Cheating the House

Winning is addictive, and money even more so. Not surprisingly, hordes of players try to cheat at the gaming tables. The trick range from palming of chips and switching of cards to rigging games with the use of electronic devices. In 1998, Dennis McAndrew and his associates pled guilty to slot machine fraud. He and his companions had used hand-held devices to program slot machines and ensure a win each time they play. They won almost $17 million before the operation's ringleader, McAndrew, was apprehended.

Stricter Security after the McAndrew Scam

After the discovery of the McAndrew scam, the gaming industry redoubled its efforts to restore their credibility. Most beefed up their security measures and had state-of-the-art surveillance camera systems installed. Cameras now monitor not just gaming tables but also escalators, elevators, retail stores, and hallways. With the exception of restrooms, just about every area in a casino, or a hotel with a casino, is put under strict surveillance. Additionally, cameras guard both front and back entrances of casinos.

Other casinos also integrate to their surveillance camera systems a means for asset tracking. Wireless motion sensors are attached to gaming machines and any attempt to move these will trigger an alarm.

Regulations on Use of Surveillance Camera Systems

Gaming commissions now recognize the value of integrating surveillance camera systems with risk management. The federal Minimum Internal Control Standards (MICS) specify 20 frames per second as the minimum recording speed of surveillance camera systems. Moreover, it specifies that all captured images be of sufficient clarity.

Gaming commissions, however, are not at all certain images captured in surveillance systems will be admissible in court. Most industry experts and gaming boards believe DVR evidence will be acceptable, but a case is yet to prove or disprove this.

Still, gaming commissions continue to prescribe the use of surveillance camera systems. After all, no matter how sophisticated gaming joints' surveillance camera systems may be, or how painstakingly each camera monitors every inch of the gaming floors, or how many personnel scrutinize the goings-on of each table, there will always be someone who tries to beat the system. Frequently, they fail and get caught. Every now and then, one succeeds and actually makes money out of a scam. With surveillance camera systems, however, apprehending con artists becomes a question of when, not if.

How Does Flash Work On A Digital Camera - Uses For Camera Flash

Use of the flash in a camera can be perplexing to novice photographers. Many are not aware of the limits to the area its light can reach. This means that up to a certain distance the flash will be useful; beyond that, having the flash on won?t do any good.

Parents taking shots of their children 50 feet from the stage in a dark school auditorium are a case in point. They find out later that they?ve gotten pictures of the heads of the audience in front, with the kids hardly visible in the background.

This happens because the subject is too far from the photographer?s camera. Light from the flash isn?t strong enough to reach the distance. The flash illuminates only the area it can, and that?s what the camera captures.

Digital cameras generally have more limited flash ranges than either a point and shoot or a digital single lens reflex (DSLR). Of the three, the more powerful and costly DSLR has the longest flash range, but it, too, has its limits.

In most point and shoot cameras, the built-in flash is capable of illuminating a space of from five up to 10 feet away. Higher-end models might manage 15 or 20 feet, but they are not that common.

DSLR cameras may come with a built-in flash that can light up objects as distant as 30 feet or more. However, that depends on the camera's quality, the flash and on what the camera settings allow. When in the default automatic mode, most built-in DSLR flashes reach only between 10 and 15 feet.

If you?re part of the audience in a concert or a school performance, chances are you?re seated too far away for your camera's flash to be of any use. Moving closer, to within your camera?s flash range, will help. So will changing a few settings, if your camera allows it. Your camera has its own set of features that may be different from other models, so you might have to read the manual to find out what can be done to make it work optimally for your specific need. In this case you want the flash to illuminate as far as it can.

In many instances, simply putting the camera on a tripod then turning the flash off may be the best course of action you can take. Rather than lighting up heads in front of you with a flash, the camera will make adjustments for the dark area it will shoot if it is set on automatic mode. Look up the manual if you don?t know how to turn off the camera's flash. Most cameras keep theirs turned on when in the automatic picture mode.

Nash Editions: Photography and the Art of Digital Printing (VOICES)

Nash Editions: Photography and the Art of Digital Printing (VOICES)
"This is the magnum opus on digital printing and the book to read before color calibrating your monitor or wondering about differences in pigmented and dye-based inks. With little in the way of “how-to,” the book focuses more on why and showcases eloquent photographs, including a heartbreakingly beautiful portrait of Marilyn Monroe, a naked World War II bomber tail gunner, and the inevitable “Emperor’s New Clothes” work. Equally heartbreaking for far different reasons is Henry Wilhelm’s essay “A History of Permanence” that includes a section called “The Totally Lost Kodacolor Era” that will leave you stunned by the corporate callousness that’s described. This book not only deserves to be on the bookshelf of anybody who cares about photography, it deserves to be read." -- Joe Farace, Shutterbug

Most of us know him as one member of the band Crosby, Stills, Nash and Young, but what you may not know is that at the same time Graham Nash was rocking the world, he was also pursuing a parallel career in photography and digital imaging. Nash Editions—the world’s premier fine-art digital printmaking studio, which Graham co-founded with R. Mac Holbert—represents the pinnacle of those efforts. This book uses thought-provoking essays and glorious artwork to sum up not only Nash Editions’ achievements but also the state of fine-art digital printmaking. After a brief history of printmaking, you’ll reach the heart of the book: an essay by Holbert on the genesis of Nash Editions and fine-art digital printing (which details the studio's interactions with major artists like David Hockney); an essay by MoMA consultant Henry Wilhelm (which includes a technical comparison of traditionally and digitally prepared prints); and commentary from Nash Editions artists. The book’s more than 100 illustrations include Nash Editions artwork, photos of artists in the studio, images of the machines used in digital printing, and illustrations of the proofing process.

Customer Review: A history of inkjet printing

I found this book to be quite a good read, but it should looked at as a historical work first. However the amount of text in this book is a lot less than you might expect, probably less than 50% of the book is written material. The remainder consists of wonderful prints from many artists.



I did enjoy it, but it should be purchased understanding the odd format, a few essays, all well written. With many prints, not all are photographs. The Wilhelm essay on history of print longevity is especially good.

Customer Review: history

The history of digital photography has twists and turns, and the Nash Editions book gives us a record of some of the key events. Worth reading, and the images are splendid.

Langford's Starting Photography, Fifth Edition: A guide to better pictures for digital and film camera users

Langford's Starting Photography, Fifth Edition: A guide to better pictures for digital and film camera users
'The' Focal Press introductory photography book. This authoritative classic was originally written by a leading photography writer and lecturer, Michael Langford, and has been updated by lecturer and best-selling author, Philip Andrews, for today's beginning photographer. All the core basics are included: how to select and compose a good picture; how different cameras operate, whether film or digital; how to use the camera's controls - shutter speed, focus, zoom, flash etc; advice on how best to tackle different subjects - people, places, animals, landscapes, or close-ups, as well as invaluable scanner and printing techniques.

Customer Review: disappointing

This book's redeeming quality is that it is inexpensive for a beginning photo text. And I like some of the British vocabulary, words like "oddments". Unfortunately, the book has the feeling of a technical manual. The images are mediocre at best, and the usage poor. Some of the glossary definitions are confusing and unclear.



The photography in the book reminds me of cheap royalty-free stock imagery, most of which provide good examples to prove technical points, but are by and large uninspiring, predictable, and lacking in personal style. I think students need to look at good photography, this text does not have inspiring, compelling work in it.



In an age where space for photography keeps diminishing, good usage is more vital than ever to the medium to provide impact. I couldn't find a single image that was used even a half page, let alone full page or doubletruck. I found it fitting that the author was credited with having photos on postage stamps. The images in the book are even more diminished by dropped-in text and distracting color borders and boxes.



While it provides a good deal of necessary and accurate information, Langford has no section on history of photography or masters of photography. It doesn't include any historical or master's work in any context. The reproduction is somewhat poor, poor enough that an example showing the difference between ISO 100 and 800 doesn't read. Lastly, Langford's example of presenting photo packages is what I would use as 'what NOT to do" when laying out a photo page.

Customer Review: A Great Publication

This book is very informative about all aspects of Photography and give a very clear understanding about Photography with Film or Digital Photo Taking. Another good book for the collection.

I got this book from the library, but I liked it so much I am going to order a copy for my 13 year old. This book is both interesting and informative. It's a great beginner's guide in a fun wrapper. Yes, you can learn how to do some crazy things and make some weird photos. But more important, there are plenty of useful tips on how to take better photos to begin with. The short sections hold your attention, the plain English makes it easy to understand, and the pictures and humor really illustrate the point. Great for tweens/ early teens with their first digital cameras. Heck, I learned some stuff and I've owned digital cameras for nearly 10 years.

Customer Review: Amazing book for Elementary School Classrooms!!!

I teach computer skills at an elementary school and one of my coworkers saw this book on the PBS teacher site and said I had to have it. She was so right. My students were fighting over my only copy so I went to the principal and got some funding to buy a book for every computer station. My students have learned real computer skills in this book and had a lot of fun while doing it. Gaines teaches many of the techniques through experimental learning and the results are both instructional and hilarious!



Get this book if you want your kids to laugh while they learn!

Photography - Things to Consider Before Buying a Digital Camera

Before you are able to take the kind of photos you want to take, it is important to think about the equipment you would like to start out with. Probably the most important decision you will have to make is what kind of camera to buy. There are so many options and brands now that the whole process can seem quite overwhelming.

Before you are able to take the kind of photos you want to take, it is important to think about the equipment you would like to start out with. Probably the most important decision you will have to make is what kind of camera to buy. There are so many options and brands now that the whole process can seem quite overwhelming.

Shopping for Cameras:

If you are planning to become a serious photographer you should probably buy an SLR (Single Lens Reflex) camera. The term single lens reflex comes from the fact that the camera has a view of the subject through a single lens and that view is reflected to the viewfinder so the photographer can see exactly what is going to be in the picture. The Digital SLR's are getting so advanced that it's very hard to choose a film camera over a digital. The main advantage of an SLR camera over a point-and-shoot digital camera is the fact that you can change lenses and filters whenever you want to, although new point-and-shoot cameras have increasing optical zoom and similar capabilities. Point-and-shoot cameras are also a great idea if you just want something simple and small that is convenient to carry wherever you go.

What to Look for in Lenses:

Lenses are what your camera uses to focus on the world. All lenses are defined by their focal length and aperture. The focal length tells you what the angle of view is and how far it magnifies. The aperture is the amount of light that the camera is letting into the sensor. Any lens lower than 50 mm focal length is considered wide-angle. Any at 50 mm is considered normal. And any lens above 50 mm is considered a telephoto. But there are also zoom lenses that have a variable focal length. With a zoom lens you can cover a wide range such as 28 mm to 105 mm or 80 mm to 210 mm.

Lenses can be very expensive and very cheap and it is usually the faster lenses or the ones with the wider apertures that are the highest priced. The faster lenses are more appealing primarily because they can produce better pictures in dim light without a tripod. But it is quite possible to find great lenses at low prices. Probably the first lens you buy should be broad range zoom lens such as a 28 mm to 105 mm. The slight drawback of zoom lenses is that they are slower and they don't quite match the sharpness and contrast of a fixed focal length lens.

Do You Need any Filters?

Another very important item that you should definitely acquire is an ultra-violet filter (UV filter). It is a simple piece of glass that screws on to the end of your lens and protects it from scratches, dust, dirt, moisture and fingerprints while reducing unwanted ultra-violet light.

But when you buy a UV filter you might as well get a polarizer filter as well. A polarizer filter is most commonly used for darkening the sky by cutting through atmospheric haze. This affect can also dramatically improve the results of black and white photography. Polarizer filters are also good for removing reflections from glass or water.

Get a Tripod:

We would also strongly recommend that you buy a tripod of some kind which is vital when there is not enough light to handhold a picture. Some of the best pictures you've seen at dusk, night, or just when its cloudy have almost certainly been taken using a tripod. Tripods allow you to use your camera's full range of shutter speed and aperture combinations which can sometimes creating amazing unexpected results.

You should pick a tripod that is plenty sturdy but also convenient enough to carry wherever you might want it. You also might want it tall enough so you can look through your camera at eye level.

Some Memory Card Details:

Memory cards are extremely convenient with digital cameras but you need to make sure you have all the space on them that you want. It is always a good feeling to know that you can take all the pictures that you want when you think you have a good opportunity. Most SLR's take Compact Flash memory cards, smaller cameras usually either take Secure Digital memory cards or Sony memory sticks.

It is convenient to have only one format of memory card if you have multiple cameras because then you can interchange them even between a big SLR and a small point and shoot camera. The smaller cameras usually use secure digital cards and Sony memory sticks but some very nice ones use compact flash cards. One thing you must always do is remember to format the card after you unload pictures and put it back into the camera or else you won't have the full capacity of the card.

If you are looking to buy a new digital camera you should consider these things or you might have regrets later.

used camera Items For Viewing
Meade 07210 45 Degree Erecting Prism #932

Meade 07210 45 Degree Erecting Prism #932
For terrestrial observing with the ETX-90EC and ETX-125EC, the #932 Prism results in a fully correctly oriented image, instead of the mirror-image you'd see otherwise, and a convenient 45 degree observing angle.

Customer Review: Great for terrestrial, ok for astronomy

This 45 degree erecting prism is great for birding or terrestrial viewing but is not suitable for star gazing (imagine if the star is right above your head). For star gazing the prism does not reflect as much light as desired so you won't be able to see dim distant objects easily, for that I recommend star diagonal with everbrite mirror ( from televue), it will cost more but a good investment for anyone who is serious about star gazing.

Customer Review: Useful- but not for astronomy

This is a generic Pacific-rim made prism imported by Meade, and not terribly different from similar items sold by Celestron, Orion and other popular companies catering to amateur astronomers. It's a useful accessory for nature viewing, but don't try to use it for star gazing. Because of how they're constructed, with multiple reflecting surfaces, erecting diagonals lose a lot of light, something you can't afford when looking at distant, dim images. Worse, they produce ghost images- for every star or planet, you'll see a dim twin nearby. Save it for daylight use, and you'll have no problem.

Celestron Car Window Mount for Binoculars

Celestron Car Window Mount for Binoculars
Why not enjoy vibration free viewing from the comfort and shelter of your car or truck? In fact, wild life photography, nature observing and other forms of surveillance are often best accomplished while you're inside a vehicle. The car window mount with heavy duty construction attaches firmly to the partly rolled-down window of your car, providing stable support for binoculars, spotting scopes, and cameras with telephoto lenses. The vise-like base firmly attaches to your car window with two large locking screws. Rubber pads prevent scratching of window glass

Customer Review: Handy mount

I've used the mount with a full size SLR and several lenses. A 70-400mm zoom lens is probably heavier than the mount was designed for, but I've gotten some good night shots using long exposures with it.



It's quick to set up and take down and less obtrusive than using a full size tripod.

Customer Review: Car Tripod

The Celestron Car window mount worked beyond my expectations. Not only is it a very stable holder for binoculars, but it also can serve as a dolly for your home video cameras. The shots I've got look great!



The only thing is that I wish it were a little more heavy duty.. ie maybe not made from plastic parts. (the plastic is strong, it's just that it's plastic)

Digital Cameras - 10 Tips To Get Great Pictures

Photography is an art, and therefore there are no set rules for getting the perfect pictures. The following tips, however, will help to improve your photographic style, experiment, and get great pictures on a regular basis. Whether your subject is a child, a pet, or nature, try some of these tips on your next photographic foray.

1. Get on Their Level - With a live subject it is important to get at eye-level before taking the shot. For children and pets this may mean kneeling, squatting, sitting or even lying down to get on the same level as your subject. While it is fun to experiment with different angles, you will have much greater success if you look your subject in the eye.

2. Fill out the Frame - Photographs are more powerful and interesting if the subject fills out the frame. Many photographers make the mistake of being too far from the subject. It is best to zoom in close enough the that the subject reaches or goes just beyond the edges of the photo frame in your view finder. This allows the viewer to see more detail and expression, and prevents the background from taking over the photograph.

3. Get a Little Closer - When you think your shot is set, try taking a few steps closer. Get in closer to your subject will show detail and emotion that add interest to your photographs.

4. Simple backdrop - When photographing a specific subject be aware of what is going on behind them. You want to choose a backdrop that will not distract or obscure the look of the subject. Choose plain color background or simple natural greenery with few accents to really highlight your subject.

5. Use the Flash - Most people think that outdoor photos never require the use of a flash, but that is not the case. When the sun is at its brightest, can be the time when it casts the most shadow. Adding a flash on an already sunny day can even-out the shadows cast by wrinkles, strange angles, or other people. Just make sure that your camera flash is close enough to the subject to be effective.

6. Watch the Light -- Light is one of the most important factors in photo taking. When you get ready to take a shot, pause for a moment to take accounting of where the sun is and what shadows may be obscuring the view. You don't want your subject squinting into the sun, nor do you want the light so bright behind them that it makes the subject look dark in comparison.

7. Go Vertical - Don't get stuck in a rut. Many pictures would look better if you just turned them vertically. There are certain subjects that lend themselves to a vertical framing such as lighthouses, the Eiffel tower, or a beautiful tree. Try going vertical with some less likely subjects to see the difference it will make.

8. Get out of the Middle - Another common mistake photographers make is to put the subject of the photograph directly in the middle of the frame. This technique is usually not the most pleasing to the eye. Instead shift your subject to one of the four corners of the frame so that it is prominent, but not center stage.

9. Steady does it - Make sure the camera is steady when you are taking photos. A steady camera will prevent a blurry photo. If you are not the best at holding steady consider using a tripod to get a clear shot.

10. Shoot Away - If you really want to get better pictures, take more pictures, more frequently. With a digital camera it is no longer a waste to snap away. Feel free to take a lot of photos of the same subject, just varying the angle, lighting, or backdrop. Experimenting will allow you to find the tricks that work best for you, and will ensure that you will have at least a few great shots of each subject.

Stephen Johnson on Digital Photography

Stephen Johnson on Digital Photography

"We are in the Stone Age of digital photography. We've figured out how to make some tools, but it is just now beginning to dawn on us what we might do with them. I've often been frustrated at the concentration on the technical aspect of digital photography with so little discussion of the aesthetics and heart behind the image making. This book is essentially a distillation of what I've been teaching over the last 25 years."

Master photographer Stephen Johnson has been taking beautiful landscape photography for decades, and teaching others the practical art of image making since 1977. While he started out with traditional film camera techniques, Johnson is widely recognized among his peers as a pioneer of digital photography. Stephen Johnson on Digital Photography chronicles his ride on the bleeding edge of this medium's evolution, and provides a practical in-depth introduction to digital photography that offers the latest techniques for beginning and experienced photographers alike.

What sets this guide apart from other books on the topic is its approach and execution: This isn't a Photoshop book, although Photoshop has its place within the book; it's a book that a master teacher and photographer creates after a lifetime of showing others how to understand and make great photography. With 5 color photographs throughout, including black/gray duotones, and 715 illustrations reproduced with a 200 line screen, Johnson's book covers everything from:

The basics of digital photography

Film camera techniques vs. digital

Practical approaches of the filmless photographer

Techniques of the digital darkroom

A photographer ™s digital journey

Photography, art and the future

This is a holistic work (and method for teaching) that embraces the state of photographic tools and techniques, blended with suggestions and experiences on why I make photographs, Johnson says. At its best, photography rides that crest where technology and art intersect. But the deepest engagement that photography can bring remains its ability to capture and hold a moment before the lens. In this age of digital manipulation, that fundamental fact must be remembered.

Customer Review: A concise, practical, and immensely engaging book on digital imaging

'Stephen Johnson on Digital Photography' is an excellent book on the tools, techniques, science, history, and art of digital photography that will appeal to digital photographers of any skill level. Johnson is a genuine pioneer and evangelist in the field of digital photography. Drawing on over three decades of experience as an accomplished photographer, educator, and product consultant to the "Who's Whos" of the digital imaging industry, Johnson succinctly and eloquently imparts to the reader/student practical and interesting information on a variety of subjects. I found the coverage of digital camera techniques, color correction and editing, color management, and fine-art printing particularly useful. This information has truly helped me to make better photographs.



'On Digital Photography' is a timeless and inspiring book that is thoughtfully organized, richly furnished with numerous beautiful and educational 5-color photographs, and superbly bound with quality paper and a resilient binding. It's manufactured to last, which is great, as I refer to it often.

Customer Review: One of the top experts makes it one of the top books

This book starts with the basics of working with digital photography and a basic guide to digital cameras. The author does a particularly good job of discussing both the similarities and the differences in film and digital camera techniques including dealing with sensor artifact repair and sensor noise. As the leading professional digital photography software most of the examples are detailed using Photoshop. Using this product Stephen Johnson discusses how and why to adjust tone and contrast, color correction and editing, changing hue and saturation, and photographic reproduction.



Throughout the book are beautiful examples of the techniques being presented including realistic photography, sensor matched techniques, scanning camera photography, and photography as art. Mr. Johnson does not have his head in the clouds when it concerns digital photography. He realizes that there are still advances that need to be made in the area of digital photography and discusses them candidly.



Stephen Johnson on Digital Photography is a well written, easy to follow, easy to understand, and very approachable introduction to digital photography as both a science and an art form. While most books on digital photography work only with the digital darkroom options this book provides a detailed understanding of each step of creating a digital photograph including how the camera works and why it is important for you to understand how it works. He discusses how various camera features affect the end result. And because of this more complete approach to the subject as well as the quality of the information Stephen Johnson on Digital Photography is a highly recommended purchase.

His articles on Photoshop, digital processing and scanning astrophotos have been published in Sky and Telescope and other magazines, and his astronomical images have appeared in books and magazines throught the world.

Customer Review: Great for beginners; Average for Intermediate

For a beginning astrophotographer or one with the interest, this book excels. It covers every aspect from A to Z including required equipment and software to optional equipment and software. I feel that 70-75% of this book is geared towards beginners.



Intermediates like myself will find that the majority of the topics covered up to the processing chapters to be unnecessary. We already have the equipment and have been taking images. We are wanting to take our images from average to great. I did find the processing chapters useful. I have already incorporated the Photoshop tools into my processing. However, the information relating to Photoshop is limited and leaves me feeling like there is much more that Photoshop can offer.



I gave it 4 stars as the book itself, format and information is great. Most important is to try and determine if you are a beginner or intermediate astrophotographer.



Jeff

Customer Review: Excellent work

Jerry has done an excellent job with this work. It covers all of the dSLR astrophotography concepts in clear detail. I just wish it were in book rather than CD format. It is hard to leaf through CD's or to recline beside the pool with them. That, plus the high price is what brought me to give it only four stars. The content gets five stars!

Real World Camera Raw with Adobe Photoshop CS2 (Real World)

Real World Camera Raw with Adobe Photoshop CS2 (Real World)

Call it a control thing, but until recently–or, more specifically, until the availability of digital raw camera formats–you simply weren’t ready to make the move to digital photography. Raw formats, however, changed all of that by allowing you to retrieve images before any in-camera processing has been performed. Photoshop’s Adobe Camera Raw plug-in makes that process even easier by providing a standardized way of accessing and working with these uncompressed digital negatives in your favorite image-manipulation software. In the first volume devoted exclusively to the topic, best-selling author Bruce Fraser shows you how to take advantage of Adobe Camera Raw to set white balance, optimize contrast and saturation, handle noise, correct tint, and recover lost detail in images before converting them to another format. After learning about the raw formats themselves, you’ll discover hands-on techniques for exposing and shooting for digital raw, using Bridge, Adobe’s new standalone file browser, to preview images and automate tasks, and building a workflow around the digital raw process.

Customer Review: Excellent CS2 book

This book is an excellent primer on the fundamentals of Camera Raw, covering a wide array of topics in an effective manner, while also offering many places for you to explore further on your own. Although this book is now out-of-date, with Photoshop CS3 on the market as I write this, this book would still be of value to those who could not afford the current version for some reason.

Customer Review: Great book

This book was a great help getting me started on processing my RAW images. It not only explaines the differences with Camera Raw and JPEG formats,, but also goes into depth on how to edit. It has many nice illustrations, and step by step instructions. Also talks about the different saving formats,,, I would highly recommend this book if you are new to RAW.

Photography 101: Reading your Camera's Histogram

Many digital cameras provide a histogram feature whereby you can see a digital analysis of your photo immediately post-shoot and determine whether it was underexposed or overexposed. But how do you look at the histogram graph and figure out what's wrong with the image and how to correct it?

Analyzing the Histogram

A histogram on a digital camera is simply a graphical representation of all the pixels in a particular photo, where the vertical axis represents the number of pixels, and the horizontal axis represents the brightness value - the left-most part of the horizontal axis is pure black (0 brightness) with the far right part being pure white (255 brightness). You may be more familiar with the histogram if you have used the "Levels" editing option in some of the Adobe software applications.

It is important to note that the entire horizontal axis represents only 5 f/stops worth of brightness, which explains why cameras cannot expose scenes with high contrast the same way we humans can see it. Thus, the importance of using the histogram: it is a tool that warns you whether you've over or underexposed a photo.

It is also important to note that if you divide the horizontal axis into 5 zones - one for each f/stop represented, that the number of tonal values available in each f/stop zone of the histogram is not equal. In fact, the zone to the farthest right that represents the brightest tonal values captures the same number of tonal values as that of the other four zones put together!

The Ideal Histogram

In order to have detail show up in dark and light areas in a photo, and to have a photo with depth, you want to expose to the right of the histogram as far as possible without clipping highlights (as shown with a right bar on the right margin of the histogram). Otherwise, your photo's tones will be represented by fewer levels, which negatively impacts tonal smoothness and adds noise, especially in dark areas.

Underexposed Histogram

An underexposed image shows the left-most part of the histogram vertical against the upper left edge of the histogram boundary (or even left-dominated, touching the left boundary at anywhere but 0). We say that the dark end of the histogram is "clipped" because the graph is cut off prematurely on the left edge. Remember that very few tonal values are captured towards the left end of the histogram, so very little detail will be visible in the dark areas of the photo.

In general, to correct an underexposed image, you can make one or more of the following changes to your camera settings and retake the shot:

1) decrease your shutter speed to let in more light (e.g. change 1/8th second to 1/4th second)

2) decrease your aperture (e.g. change f/8 to f/5.6)

3) increase your ISO (e.g. change ISO 200 to ISO 400)

Overexposed Histogram

An overexposed image shows the right-most part of the histogram vertical against the upper right edge of the histogram boundary. We say that the light end of the histogram is "clipped" because the graph is cut off prematurely on the right edge. Such a histogram maps to a photo that is overexposed, and has lost detail in the lightest areas of the image.

In general, to correct an overexposed image, you can make one or more of the following changes to your camera settings and retake the shot:

1) increase your shutter speed to let in more light (e.g. change 1/250th second to 1/500th second)

2) increase your aperture (i.e. change f/5.6 to f/8)

3) decrease your ISO (i.e. change ISO 400 to ISO 200)

Properly Exposed Histogram for a low-key photo (i.e. mostly dark - perhaps the moon at night)

When a photo is composed of things that are mostly very dark in shade, then we call it a low-key photo. Such photos will have a histogram with the left end dominated. It can be challenging to capture such an image with low contrast and without underexposing - the histogram would show it's left edge being clipped if the photo is underexposed. An example of a low-key image would be the proverbial black cat at night.

Properly Exposed Histogram for a high-key photo (i.e. mostly light - perhaps a snow scene)

When a photo is composed of things that are mostly very light in shade, then we call it a high-key photo. These photos will have a histogram with the right end dominated. It can be challenging to capture such an image with low contrast and without overexposing - the histogram would show it's right edge being clipped if the photo is overexposed. An example of a high-key image would be a snowman in the snow.

Customer Review: Nice Binoculars

I have used and wasted alot of money on different compact binoculars like some of you have already. These have the clearest, brightest view of any of them. Time will only tell the long time sturdyness of them, but they appear to be very sturdy and well made. There easy to handle and adjust. Thumbs up for these binoculars

Customer Review: Best ones I've owned

I've had season tickets to theater and sporting events for over a decade and these are the best (of approximately 4 sets) binoculars I've had (of the same size). They are twice as expensive as some of the others - so I would expect some improvement. However, I cannot address the durability issue yet, and this was a major concern with two of my previous sets of binoculars. I keep them in my car and they seem to get permanently damaged from the car movement after a few years.

Customer Review: Good glasses to have in the canoe

My goal was to have an relatively inexpensive pair of binoculars to have with me in my canoe whenever I paddle. This pair has filled that need admirably. For my purpose the waterproof feature was necessary. The small lens lets in plenty if light during the day so that has not been a problem; I suppose there is a point towards getting dark that these would not work well but a better larger lens pair would, but certainly not at this price. I would like a slightly larger field of vision, and perhaps more weight would make holding them steady easier, but as noted for my use these are fine; mainly getting a better look at birds in the distance. Small and light makes them easy to keep around.

Don't waste your time with the fake batteries. I bought a Targus clone for my 20D and the battery died within a year. Targus support is ignoring me. I should have just stuck with Canon batteries from the very start.
