Exchangeable image file format is a standard that specifies the formats for images, sound, and ancillary tags used by digital cameras, scanners and other systems handling image and sound files recorded by digital cameras. The specification uses the following existing file formats with the addition of specific metadata tags: JPEG discrete cosine transform (DCT) for compressed image files, TIFF Rev. 6.0 for uncompressed image files, and RIFF WAV for audio files. It is not used in JPEG 2000 or GIF.
