Preparation

∫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.
