Using the Histogram

 

 

 

 

 

 

 

 

 

 

 

 

 

A histogram shows the

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

brightness distribution of an

image. The horizontal axis

 

 

 

 

 

 

 

 

 

 

 

 

represents brightness (dark at

and the vertical axis represents

 

 

 

 

 

 

 

 

 

 

 

the number of pixels.

Pictures

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) and when the image is too bright, the part to the right is cut off (bright portions).

Bright portions blink red on the LCD monitor and dark portions blink yellow.

Understanding Contrast

The graph peaks gradually 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.
