Short for Exchangeable Image File, a format that is a standard for storing interchange information in digital photography image files using JPEG compression. Almost all new digital cameras use the EXIF annotation, storing information on the image such as shutter speed, exposure compensation, F number, what metering system was used, if a flash was used, ISO number, date and time the image was taken, whitebalance, auxiliary lenses that were used and resolution.

EXIF files use the JPEG DCT format, so the image data can be read by any application supporting JPEG, including essentially all Web browsers and image editing, desktop presentation and document creation applications.
