A to Z Challenge - H

A histogram is a graphic representation of the distribution of light. Some advanced digital cameras, many dSLRs for example, will show you a histogram of the exposure of your shot before you shoot.
By looking at a histogram, you can tell if you need to adjust your aperture, shutter speed, ISO or perhaps add additional lighting via flash or other lighting unit.

Generally, the right side of histogram will be the highlight side and the left will be a the shadow side.
