How To Purchase a Digital Camera

Purchasing a Digital Camera can seem like a daunting task. All those numbers, 6.0 mega pixels, 640 x 480, 64 MB Flash memory , who can understand or convert between different cameras? This tutorial will help you understand what all those terms mean, which aspects of a digital camera you may be interested in while shopping, and be able to compare different cameras with seemingly different descriptive terms. Digital cameras allow for instant access to your pictures. Most cameras on the market have an LCD screen to view the pictures immediately. You can then choose which pictures to keep and which to delete. Using different methods, you can then send the pictures to your computer to email them, print, or store them for future use.
