DPOF: Digital Print Order Format
DPOF is a format used for recording information on a storage media (image memory card, etc.) that allows
you to specify which of the frames shot using a digital camera are printed and how many prints are made of
each image.
EV:
A number that denotes exposure. The EV is determined by the brightness of the subject and sensitivity (speed) of
the film or CCD. The number is larger for bright subjects and smaller for dark subjects. As the brightness of the
subject changes, a digital camera maintains the amount of light hitting the CCD at a constant level by adjusting
the aperture and shutter speed. When the amount of light striking the CCD doubles, the EV increases by 1.
Likewise, when the light is halved, the EV decreases by 1.
JPEG:
Joint Photographics Experts Group
A file format used for compressing and saving color images. The compression ratio can be selected, but the higher the
compression ratio, the poorer the quality of the expanded image.
Motion JPEG:
A type of AVI (Audio Video Interleave) file format that handles images and sound as a single file. Images in
the file are recorded in JPEG format. Motion JPEG can be played back by QuickTime 3.0 or later.
PC Card:
A generic term for cards that meet the PC Card Standard.
PC Card Standard:
A standard for PC cards determined by the PCMCIA.
PCMCIA:
Personal Computer Memory Card International Association (US).
White Balance:
Whatever the kind of the light, the human eye adapts to it so that a white object still looks white. On the other
hand, devices such as digital cameras see a white subject as white by first adjusting the color balance to suit
the color of the ambient light around the subject. This adjustment is called matching the white balance. A
function that automatically matches the white balance is called an Automatic White Balance function.
