Using Histogram A histogram is a graph showing the brightness of an image on the horizontal axis Number of pixels and the number of pixels on the vertical axis (distribution chart of the brightness). The histogram will help you detect the brightness of the image you have taken. For instance, the graph peak tends to appear on the left side for a darker image, and the graph peak Brightness tends to appear on the right side for a brighter (Dark) (Bright) image. In general, when the exposure meter of your image is well-balanced, the graph peaks 4 tend to appear in the middle. On the contrary, when the exposure meter gets imbalanced tending dark and bright without showing a neutral brightness, the peaks appear not in the middle but on both sides.
