A 3-megapixel camera generally will provide the best balance of features vs. cost for most people's needs. But don't get caught up in the "megapixel myth" when comparing specs on cameras. What you need to know is the true megapixel count of the camera, taken directly from the CCD (charge coupled device, the digital sensor in the camera).

Some camera manufacturers artificially boost the megapixel counts for their cameras using interpolation, which raises the resolution of digital files through mathematical calculations with software. It works, but there is always a loss of quality. Beware if the fine print on the package says "3 effective megapixels," indicating it's not a true measure.

Zoom lenses: Don't be fooled by digital zoom numbers that, once again, use mathematical manipulation. Determine the camera's true optical zoom magnification. If you use the digital zoom feature on any camera, you will be disappointed with the sharpness and overall quality of the images.

Storage cards: Choose a camera that has removable storage cards. Cameras with fixed, internal storage capacities limit the number of pictures you can take while away from your computer. There are many different types of digital cards. The Compact Flash card, however, has emerged as the standard for many cameras of 3 megapixels and above.

Standard batteries: Look for cameras that use rechargeable batteries, but stay away from proprietary batteries, if possible. Buying a camera that uses AA batteries or a CR-5 battery pack will make it easier to find batteries when you need them.

Beware of novelties: Some cameras can play MP3 files, while others can make short movies with sound. These features may seem like enhancements, but it's better to choose a camera that will consistently make good, sharp pictures than to choose one for these extra features.

Shop around: The Internet is a great source for deals on digital cameras, but you have to be careful. For example, some low prices on the Web are "gray market" merchandise, meaning the warranty may not be valid in the United States. Search dealtime.com or pricegrabber.com for the camera you want, and pay attention to the ratings for the various dealers.

The bottom line: Make a budget. Include funds for extra batteries, extra storage cards and perhaps a digital card reader. Don't let the sales rep talk you into extra accessories when you make your purchase.
