• Check the histogram on your camera that you haven’t “clipped” out tones

Some digital cameras have A histogram helps you to decide if you have exposed a photo correctly or if the picture you are about to take is exposed correctly.

Gaps on one side or the other of the graph indicate that the photo is either under or over exposed.
