Camera Sensitivity - Iso; Flash Range And Camera Sensitivity - Minolta Dimage X20 Instruction Manual

CAMERA SENSITIVITY - ISO

Five camera sensitivity settings can be selected with a still image: Auto, 64, 100, 200, 400; the
numerical values are based on an ISO equivalent. ISO is the standard used to indicate film sensitivi-
ty: the higher the number, the more sensitive the film. Sensitivity can be changed in section 1 of the
recording-mode menu.
The auto setting automatically adjusts the camera sensitivity to the
light conditions between ISO 64 and ISO 200. When any other set-
ting than auto is used, "ISO" and the set value will appear on the
LCD monitor.
A specific sensitivity setting can be selected. As the ISO value dou-
bles, the camera sensitivity doubles. Like grain in silver-halide film
that increases with speed, noise increases with the sensitivity in dig-
ital imaging; an ISO setting of 64 will have the least noise and 400
will have the most.

FLASH RANGE AND CAMERA SENSITIVITY

Because of the optical system, the flash range is not the same at the lens' wide-angle position as it is
at the telephoto position.
