In digital photography, the Camera Image File Format (CIFF) file format is a raw image format designed by Canon, and also used as a container format to store metadata in APP0 of JPEG images. [1] Its specification was released on February 12, 1997. [2]
DCT compression is used in the JPEG image standard, which was introduced by the Joint Photographic Experts Group in 1992. [14] JPEG compresses images down to much smaller file sizes, and has become the most widely used image file format. [15] The JPEG standard was largely responsible for popularizing digital photography. [16]
RAW is not a standardized format, in fact, RAW-formats even differ between camera models from the same vendor [citation needed]. Data in a RAW-file is structured according to the Bayer filter's pattern in cameras that use a single image sensor. Debayering, the process of obtaining bitmap data from a RAW-image is always a lossy operation.

The JPEG filename extension is JPG or JPEG. Nearly every digital camera can save images in the JPEG format, which supports eight-bit grayscale images and 24-bit color images (eight bits each for red, green, and blue). JPEG applies lossy compression to images, which can result in a significant reduction of the file size.

Exchangeable image file format (officially Exif, according to JEIDA/JEITA/CIPA specifications) [5] is a standard that specifies formats for images, sound, and ancillary tags used by digital cameras (including smartphones), scanners and other systems handling image and sound files recorded by digital cameras.
