Histogram Palette

A histogram gives an illustration of how the pixels in your image are distributed by drawing a graph showing the number of pixels for each color intensity level. The tonal range is also shown in the histogram and it’s distributed and concentrated in the following order:

1. Low-key image (tonal range): the details of the image are concentrated in the shadows.
2. Average-key image (tonal range): the details of the image are concentrated in the midtones.
3. High-key image (tonal range): the details of the image are concentrated in the highlights.

Tip: by default the histogram palette displays the tonal range of the whole image that you are using. If you want too see the graph of each channel, click on the options button under the close button in your histogram palette you'll get the following viewing option:
