Histogram
A histogram is a graph indicating the image’s
brightness distribution. The horizontal axis indicates
the brightness level (darker on the left and brighter on
the right), while the vertical axis indicates how many
pixels exist for each brightness level.
The more pixels there are toward the left, the darker
the image. And the more pixels there are toward the
right, the brighter the image.
If there are too many pixels on the left, the shadow
detail will be lost. And if there are too many pixels on
the right, the highlight detail will be lost. The tones in-
between will be reproduced.
With the image’s histogram, you can check how
accurate or lopsided the exposure is and how rich the overall tonal range is.
