Understanding Brightness
If the brightness is correct, the graph peaks in the middle. If the image is
too dark, the peak is on the left side, and if it is too bright, the peak is on
the right side.
When the image is too dark, the part to the left is cut off (dark portions with
no detail) and when the image is too bright, the part to the right is cut off
(bright portions with no detail).
Bright portions blink red on the monitor and dark portions blink yellow
when Bright/Dark area is on.

Understanding Contrast
The graph peaks gradually in the middle for images in which contrast is
balanced. The graph peaks on both sides but sinks in the middle for images
with a large difference in contrast and low amounts of mid-level brightness.
Understanding Color Balance
Distribution of color intensity is displayed for each color in the RGB histogram.
The right side of the graphs look similar for images that have White Balance
adjusted well. If only one color is lopsided to the left, that color is too intense.
