Camera Sensitivity - Iso; Flash Range And Camera Sensitivity - Konica Minolta DiMAGE Z3 Instruction Manual

CAMERA SENSITIVITY - ISO

Five camera sensitivity settings can be selected: Auto, 50,
100, 200, and 400; the numerical values are based on an
ISO equivalent. ISO is the standard used to indicate film
sensitivity: the higher the number, the more sensitive the
film. Camera sensitivity is set in section 3 of the P, A, S, and
M menus (p. 44).
The auto setting automatically adjusts the camera sensitivity to the light conditions
between ISO 50 and 200. When any other setting than auto is used, "ISO" and the set
value will be displayed on the monitor.
A specific sensitivity setting can be selected. As the ISO value doubles, the camera
sensitivity doubles. Like grain in silver-halide film that increases with speed, noise
increases with sensitivity in digital imaging; an ISO setting of 50 will have the least noise
and 400 will have the most. An ISO setting of 400 may allow the camera to be hand-held
in low-light conditions without the need of a flash. The affect of noise with exposures of
one second or longer is reduced by the noise-reduction function in section 3 of the setup
menu (p. 90).

FLASH RANGE AND CAMERA SENSITIVITY

The flash range is measured from the front of the lens. 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.
