Digital Camera Features

Resolution is defined as the number of discreet points of light (pixels) captured per shot. The larger the number the more you can enlarge a picture without it going fuzzy. For good quality 5 x 7 pictures, a 2 –3 megapixel camera will do however for larger pictures you will need a 3 megapixel or greater digital camera. Must cameras have a built-in flash called a strobe with a limited range (10 – 14 feet). Some cameras have a red-eye reduction feature while other more expensive models allow you to adjust the illumination level with a fill flash feature. The point and shoot cameras come with a fixed focus lens that focuses on everything from 4 feet to infinity. Intermediate cameras have auto-focus which allows you to focus on a specific area. Optical zoom features allow you to focus on a distant object. Professional digital cameras can also use optional wide-angle or telephoto lenses and will allow for fine-tuning of the shutter speed.
