About the Exposure
• 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.
• When the values are concentrated to
the left as A, the picture is under
exposed.
• When the values in the histogram are
distributed as B, the exposure is
adequate and the brightness is
well-balanced.
• When the values are concentrated to
the right as C, the picture is over
exposed.
