EXIF.

EXchangeable Image File. An image format created by JEIDA, the Japan Electronic Industry Development Association, and supported by nearly all digital cameras.

It’s essentially JPEG with a number of extra marker tags (metadata) containing useful shooting information about the photo. EXIF files can therefore be read by JPEG-compatible programs, but software which understands EXIF tags can extract that data as well. Common bits of information include shutter speed, aperture, metering mode, camera manufacturer, focal length, ISO speed, white balance, flash on/off, etc.

cf. aperture, DPOF, EXIF, focal length, JPEG, ISO, shutter speed, white balance.
