Using Histogram A histogram is a graph showing the Number of pixels brightness of an image on the horizontal axis 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 Brightness image, and the graph peak tends to (Dark) (Bright) appear on the right side for a brighter image. In general, when the exposure meter of your image is well- 4 balanced, the graph peaks 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.

Taking Pictures
4
A histogram is a graph showing the
brightness of an image on the
horizontal axis 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 tends to
appear on the right side for a brighter
image. In general, when the exposure meter of your image is well-
balanced, the graph peaks 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.
