Understanding ISO takes patience, but it is the key to good photography. ISO stands for International Standards Organization, the standardized industry scale for measuring light. In Digital Photography, ISO measures the sensitivity of your camera’s image sensor. In this free video, world renowned outdoor photographer Ian Plant gives you guidance on understanding ISO. As he explains, the lower the ISO number the less sensitive your camera is to light and the finer the grain.

If you are in a shooting situation where the light is changing fast such as sports or wildlife, you might want to use your camera’s auto ISO setting.
