∫ 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 overexposed.
