Using Histogram

A histogram is a graph showing the

 

 

 

 

 

 

 

 

 

 

 

 

 

 

brightness of an image on the

pixels

 

 

 

 

 

horizontal axis and the number of

 

 

 

 

 

pixels on the vertical axis (distribution

 

 

 

 

 

of

 

 

 

 

 

chart of the brightness). The histogram

will help you detect the brightness of

 

 

 

 

 

the image you have taken. For

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.
