About ISO Speed

ISO speed is an index nunnber representing the photosensitivity of silver-halide film. Digital

oameras do not use film, but their photosensitivity is commonly described in terms of “ISO

equivalent” speed settings. (-»-ISS)

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 ECS D30 provides ISC-equivalent speed settings from ISC 100 to ISC 1600, in

one-step increments.
