Displaying the Histogram
The following procedure displays a histogram of an image's
luminance components. The histogram is a tool you can use
to check the exposure of an image.
1.
Align the POWER/Function Switch with PLAY.
2.
Use [ ] and [ ] to display the image whose
histogram you want to view.
3.
Press SET/DISP a number of times until the
histogram appears.

IMPORTANT!
• The histogram does not appear during movie play-

• In the case of a panorama image (page E-102), the
histogram is displayed for the first image of the pan-
orama only.
• Use of the flash or multi-metering, as well as certain
shooting conditions can cause the histogram to indi-
cate exposure that is different from the actual expo-
sure of the image when it was recorded.
About the histogram...
The histogram is a graph of pixel luminance levels in terms
of the number of pixels. The vertical axis represents the
number of pixels, while the horizontal axis represents lumi-
nance. The information on the histogram can be used when
correcting or editing the image to determine whether image
details include enough shadows (left side) midtones (cen-
Histogram
ter), or highlights (right side). The histogram also makes it
easy to visualize the color tone range of an image, which
makes it a valuable reference tool when touching up the im-
age.
