Displaying a histogram
A histogram is a graph showing the
brightness of the pixels contained in an

or SCN.
b Press DISPLAY to display the
histogram.

the histogram.
Adjusting the exposure to the + side shifts
the histogram to the right side.

the histogram to the left side.
The histogram also appears when the mode dial
is set to or M, but you cannot adjust the
exposure.
The histogram also appears when you press
DISPLAY while playing back a single image
(page 33) or during Quick Review (page 21).

cases:

histogram of the image displayed on the screen
at the that time. A difference occurs in the
histogram before and after you press the shutter
button. When this happens, check the histogram
while playing back a single-image or during
Quick Review.

following cases:
