When Histogram is on, a histogram appears 
in the lower right corner on the picture 
display. A histogram is a graph indicating 
the number of pixels on the vertical axis 
and the brightness on the horizontal axis 
(from left to right, shadows (dark areas), 
midtones, and highlights (bright areas)).

By using the histogram, you can determine the brightness of an image 
without being affected by the brightness around the picture display. 
This also helps you correct for areas that are overly bright or dark.

If the histogram has only peaks on the 
right side, this picture is overexposed 
with too many pixels only for highlight 
sections.

If the histogram has only peaks on the left 
side without anything else, this picture 
is underexposed with too many pixels 
only for shadow sections. Refer to this 
histogram when correcting the exposure.

•  The histogram displayed on the picture display is for reference only.
•  After taking a picture, you can correct its brightness and contrast by making 

adjustments to the histogram (GP.70).

•  Depending on the shooting conditions (use of the flash, dark surrounding light, 

etc.), the exposure level indicated in the histogram may not correspond to the 
brightness of the shot image.

•  Exposure compensation has its limitation. It does not necessarily achieve the 

best possible result.

•  A histogram with peaks in the center may not necessarily provide the best result 

to suit your particular requirements. For example, an adjustment is required if 
you want to underexpose or overexpose the image.

•  For information on how to correct the exposure compensation, see P.62.
