Using the On screen Histogram to Check Exposure



Displays a histogram on the monitor screen which you can use to 
check the exposure of an image before you shoot it. You also can 
display the histogram in the PLAY mode for information about the 
exposure levels of images.


• A centered histogram does not necessarily guarantee optimum exposure. The 

recorded image may be over-exposed or under-exposed, even though its 
histogram is centered.

• Due to the limitations of exposure compensation, you may not be able to achieve 

an optimum histogram configuration.

• Use of the flash and certain shooting conditions can cause the histogram to 

indicate exposure that is different from the actual exposure of the image when it is 

• The histogram cannot be displayed during high speed movie recording.


How to Use the Histogram

A histogram is a graph that represents the lightness of an image in terms of the 
number of pixels. The vertical axis indicates the number of pixels, while the horizontal 
axis indicates lightness. If the histogram appears too lopsided for some reason, you 
can use EV shift to move it left or right in order to achieve better balance. Optimum 
exposure can be achieved by EV shifting so the graph is as close to the center as 
possible. For snapshots, you can even display individual histograms for R (red), 
G (green), and B (blue).
