What is JPEG and TIFF?
Two most popular picture storage formats used by digital cameras are JPEG and TIFF. The JPEG format uses lossy compression (some data judged by the algorithm to be less important to the human viewer is discarded) to achieve small file sizes. The TIFF format uses lossless LZW compression so no information is lost, however the pictures are typically much larger. High-quality JPEG setting is preferable for most uses.
