Digital SLR Camera Basics


An abbreviation of “Joint Photographic Experts Group,” an image data format that compresses images to reduce file size and allows more images to be stored. The amount of compression can be chosen from “fine” (compression ratio 1 : 4), “normal” (compression ratio 1 : 8), and “basic” (compression ratio 1 : 16). High compression ratios reduce file size, allowing more images to be stored, but also make the loss of image quality associated with compression more evident.
