Photograph Without Flash in Dim Light

Using a flash for pictures in dim light isn't always possible or appropriate. If the subject is too far away for light from the flash to reach it or if the flash would disrupt the scene, you can increase the ISO setting to help the camera "see in the dark".

In the dim light of a large classroom, I used ISO 12,800 to get a proper
exposure of the falcon as well as freeze the motion of its wings.

Higher ISO numbers increase the camera's sensitivity to dim light and help you make pictures without the flash or a tripod.

After dark in San Francisco, I needed ISO 6400 to make a sharp, hand-held
picture of the lighted sign over Ghirardelli Square.
