ISO speed is an index number representing the photosensitivity of silver-halide film. Digital
cameras do not use film, but their photosensitivity is commonly described in terms of “ISO
equivalent” speed settings. (→132)
The higher the number, the greater the sensitivity. Higher speeds are better for taking pictures
of moving subjects or in dim light, but the pictures will also contain more noise and so will be
less sharp. Conversely, lower speeds are less suited to moving subjects or dim conditions, but
produce sharper, more detailed images.
The Canon EOS D30 provides ISO-equivalent speed settings from ISO 100 to ISO 1600, in
one-step increments.
