Reading a histogram
Understanding image histograms is probably the single most important concept to
becoming familiar with Photoshop. A histogram can tell you whether your image has been
properly exposed, whether the lighting is correct, and what adjustments will work best
to improve your image. It will also indicate if the image has enough tonal information to
produce a quality image. You will reference the Histogram panel throughout this lesson.

If your Histogram panel is not visible, choose Window > Histogram. The Histogram
panel appears.
A histogram shows the tonal values that range from the lightest to the darkest in an
image. Histograms can vary in appearance, but typically you want to see a full, rich,
mountainous area representing tonal values. See the i gures for examples of a histogram
with many values, one with very few values, and the images relating to each.
