∫ Histogram
• A histogram is a graph that displays
brightness along the horizontal axis (black
to white) and the number of pixels at each
brightness level on the vertical axis.
• It allows you to easily check a picture’s
exposure.
• It is very useful if manual adjustments of
the lens aperture and shutter speed are
available, especially in those situations
where automatic exposure may be difficult
due to uneven lighting. Using the
histogram feature allows you to get the
maximum performance from your camera.
A When the values are concentrated on
the left, the picture is under exposed.
B When the values are distributed evenly,
the exposure is proper and the
brightness is well-balanced.
C When the values are concentrated on
the right, the picture is over exposed.
Example of histogram
A Under Exposed
B Properly Exposed
C Over Exposed
