It is essential when you compare digital camera options to understand the issues of image resolution, which is measured in megapixels. Basically, the more megapixels, the higher the resolutions of the final image but you definitely need to compare digital camera images with your actual requirements. This is best done if you compare digital camera resolution with the size of the images that you want to print and you will find that a 1-mg camera can create a 3-by-5-inch (7.5 by 13 cm) photo-quality print; a 2-mg camera will make a 5-by-7-inch (13 by 18 cm) print; a 3-mg camera will make an 8-by-10-inch (20 by 25 cm) print, and a 6-mg camera will make a 9-by-13-inch (23 by 33 cm) print.
All of the cameras that you are considering when you compare digital camera features should have an LCD screen for viewing pictures, a built-in flash, a timer, and a time/date stamp on even the most basic camera. You should also look to compare digital camera packages that have optical zoom, not digital, if you need a zoom capability and most midrange cameras should have high-quality optical zoom lenses but it is still worth checking to make sure.
