Dynamic range is the camera sensor’s ability to capture detail in very bright and very dark parts of a scene. Cameras (or sensors) with a low dynamic range record dark shadows as a solid black or bright highlights as a featureless white.
The histogram is a graphical display of the brightness values in the picture. The darkest tones are at the left and the brightest on the right, and the vertical bars show the number of pixels for each brightness value. Histograms are an invaluable exposure aid when taking pictures, and when editing them later.
Histograms just show you what’s happening in your images, they’re not there to tell you what to do. But there’s an old adage from the days of film photography that you should still be able to see some detail in the darkest and brightest parts of your pictures, and that’s carried through into digital photography.

Levels and curves can both be used to adjust the contrast in photos, but how are they different, which should you use and is one better than the other?
There’s this idea in digital photography that your histogram must never be clipped, and that it should always fit – just – within the maximum width of the scale. And sometimes we work so hard to recover shadow and highlight detail to prevent clipping, that we end up with an image that has lost its […]
