Abbreviation for auto exposure. It is an automatic metering and exposure system that sets the
optimum exposure (shutter speed and/or aperture) based on the reading by the built-in
exposure meter.

Abbreviation for auto focus. It enables the camera to focus the subject automatically.

CF card is the small, card-shaped storage media used to record images taken by the EOS-1D.

This indicates the film’s sensitivity to light. It is expressed as a number following “ISO” such as
“ISO 200.” The higher the number, the higher the sensitivity to light. Digital cameras also use
the same ISO speed standard used by film-based cameras.

Abbreviation for Joint Photographic Experts Group. It is an image file format with various
compression levels. The higher the compression rate, the lower the image quality, when the
file is expanded (restored).

This is an image file format that saves the image as is when captured by the camera’s CCD
sensor. It is geared for image processing with a personal computer.
It uses lossless compression. By using the driver software’s image-processing parameters,
you can obtain the desired image characteristics.

Color matching standard jointly developed by Microsoft and Hewlett-Packard. Cameras,
monitors, applications, and printers which comply with this standard are able to reproduce
colors in the same way. (The “s” stands for standard.)
