∫ 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 the camera user to easily check
the way a picture is being exposed.
• 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 will allow you to get the
best performance from the camera.
A When the values are concentrated to
the left, the picture is under exposed.
B When the values in the histogram are
distributed evenly, the exposure is
adequate and the brightness is
well-balanced.
C When the values are concentrated to
the right, the picture is over exposed.
