Today's images are getting bigger and better than ever. If you were used to shooting 5 MP JPEGs and then jumped to the 8 MP RAW files that some of today's $900 DSLRs shoot, your file size will increase from about 1.5 MP to between 5.5 MP (saved to DNG) and 8 MP (Canon CR2 file in 16-bits [only 12-bit of image data] for 8 MP image). Once you've processed that file, you'll have between 5 and 15 layers and several will be image layers. You could easily end up with 100 MB files for all your best imagesthat is, the ones you have the incentive to really put some effort into processing to perfection. For example, last year I shot some 8,000 images in CR2 format. Let's say the toss-out rate is about 15 percent. That still leaves 6,800 images I have to store and find... Still, this isn't too bad. I've used only about 54 gigabytes of storage so far. If about 10 percent graduate to stardom, that's only 680 images. The problem is, each image is going to need about 100 MB of space by the time I finish editing them nondestructively. So I need another 54 GB for the special 10 percent that survive. You begin to see the problem when you realize that a lot of pros shoot at least 10 times as many images as I do. The bottom line is that you need to start with a very fast computer with lots of storage. For either Windows or Mac, I'd suggest a dual core or 64-bit processor running at around 2.4+ gigahertz. Plug at least 1 MB of RAM into the motherboard and move up to 2+ MB as quickly as you can afford it. Every time you see a sale on 250500 GB external hard drives, get yourself another. External drives make the most sense for storing large image libraries. They're easy to copy to one another for backup and they can easily be moved from computer-to-computer. At sale prices, you'll pay around 75 cents per gigabyte or $180 for a 250 GB drive. Make backups by copying one drive to another while you're sleeping. External hard drives love to crasha much unpublicized factand you don't dare risk your valuable images. Be very careful to follow the prescribed routines for installing the software for the drives, plugging them in and out, and turning them on and off. When it comes to your ability to see your images clearly so you can judge them accurately, you'll want to pay attention to your video system. You want a high-performance video card. The NVIDIA GeForce, ATI Radeon, and Matrox are presently considered best-in-class. Check out current web reviews and information for what is considered state-of-the-art. (You don't need the top of the line cards that are intended for the gamers' market.) It's also time to move up to a state-of-the-art flat-panel screen unless you're doing pre-press work in a production house. There are now excellent 19-inch models on the market for less than $300. Look for a model with a contrast ratio better than 500:1 (the higher the contrast ratio, the better) and the widest possible viewing angle. Most of us will gladly trade a tiny margin of brightness and contrast ratio for a steadier image that is much easier on the eyes and has virtually no screen glare. Besides, you need the extra room on your desk for a Wacom graphics tablet and all those hard drives. Given the resolution that pros are expecting from their images, I wouldn't even consider a screen size smaller than 19 inches. If you have an older 17-inch monitor, consider getting a dual monitor video card and using the second monitor strictly for menus, Bridge, or DAM software. Speaking of image backup, don't even think about anything less than a state-of-the-art DVD writer8X write speed minimum. CDs just aren't capacious enough for contemporary files, and you have to spend way too much of your time swapping disks when they fill. Do not write on the disks with Sharpie markers or paste labels on them. Instead, go to your local office supply store and ask for acid-free markers. They look just like Sharpies, cost a bit more, but won't send your images to heaven when you least expect it. If you travel or hike while shooting, a high-horsepower laptop is a lifesaver. Look for the following features: 1+ MB RAM, 100+ GB HD, 15.4- or 17-inch widescreen, DVD writer, built-in WiFi, and built-in card reader. Even a duo-core 64-bit processor is an affordable option nowadays. You should be able to get all this for around $1,200 in a Windows laptop or for around $2,200 in a Mac laptop.

Following these suggestions will improve the quality of your action shots: First, set your camera at its highest resolution. You will probably want to crop your image later to bring the action closer. Having extra pixels actually extends the reach of your lens, which is very helpful for this type of photography. The key to "stopping action" is to use a fast shutter-speed setting. Typically, you should use a speed of at least 1/250th, 1/500th, or 1/1000th of a second. The programmed autoexposure ...
2. How Do I Shoot Infrared Images
Infrared photography has been around for a long time, but capturing these stunning pictures on film required true perseverance. Digital imaging has changed all of that. Shooting infrared photos has never been easier or more fun. When you shoot infrared, you're actually dealing with a spectrum of light that's outside our normal range of perception. But with the assistance of a special filter, such as an IR 87 or Hoya R72, many digital cameras can produce the telltale dramatic effects, including a darkened sky, vivid clouds, and ...

6. How To Prevent Red Eye Effect
Your subjects are vulnerable to red eye in dimly lit rooms when their pupils are open wide. The effect is actually caused by the light from the flash bouncing off the retina and being reflected back into the picture-taking lens. Point-and-shoot cameras are notorious for causing red eye, because the flash is so close to the lens; this makes for a perfect alignment to catch the reflection from the retina. Even though many cameras provide a setting to reduce red eye, they don't always work well and actually can be irritating...
7. How Do I Take Passport Photos and Self Portraits
Some people may think that turning the camera toward yourself is the height of narcissism, but sometimes you need a shot and no one is around to take it for you. Headshots for passport photos and résumés are typical scenarios for the emergency self-portrait. Start with the basics: make sure your hair is combed, your collar is down, your shirt is clean, and your teeth are free of spinach (and lipstick!). Then find a location with a pleasing, uncluttered background. Put the camera on a tripod, and set it to fo...
8. How To Take Pictures from the Stands at Sporting Events
Speaking of the flash, how many times have you seen hundreds of cameras firing off from the stands during a sporting event in a large stadium? Alas, what a waste of film, battery power, and space on memory cards. The flash range of most point-and-shoot cameras is about 10 feet. That means that if you're shooting from the stands, you're illuminating a couple of rows of seats in front of you, and that's about it. Instead, turn off your flash and use existing-light techniques. If you can adjust your camera's ISO setting bump ...

First, start with the magic rules for great outdoor portraits: Try adding supple...
10. Tips On How To Shoot in Museums
Museums, aquariums and natural habitat parks provide opportunities for unusual shots. They also present some difficult challenges for the digital photographer, but nothing that can't be overcome with a little ingenuity. Before you get too excited at the prospect of shooting beautiful works of art in a museum, be sure to ask if it's OK.
