The camera provided clean noise-free results even at ISO settings up to 1600.

The ISO 50 setting reduces dynamic range by a stop in the highlights.

Some cameras feature high ISO settings and modes for taking pictures in low light without a flash.

So in dark conditions you can increase the ISO setting and get sharper, clearer images.

The main change from last year's model involves the range of ISO settings, which are comparable to film speed ratings.

An ISO setting of 400 and above generally works best.

Or, alternatively, you can increase the ISO setting (see below).

So the higher a digital camera's ISO settings, the more able it is to nail the action shot.

The unit's images have very little noise, even at high ISO settings.

Digital cameras usually have variable ISO settings that provide additional flexibility.
