Histogram Display

When histogram display is on, a histogram

appears in the lower right corner on the LCD

monitor screen.

A histogram is a graph indicating the number

of pixels on the vertical axis and the

brightness on the horizontal axis. The

brightness is shadow (dark), halftone, and

highlight (light) from the left.

By using the histogram, you can judge the brightness of an image without

being affected by the brightness around the LCD monitor. This also helps you

correct for areas that are overly bright or dark.

If the histogram has only peaks on the right

side without anything else, this picture is

over-exposed with too many pixels only for

highlight sections.

If the histogram has only peaks on the left

side without anything else, this picture is

under-exposed with too many pixels only for

shadow sections.

Correct the exposure to an appropriate level.

Note

• The histogram displayed on the LCD monitor is for reference only. 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.

• The histogram having peaks in the center part does not necessarily provide the best result

to suit your particular requirements.

For example, an adjustment is required if you want to intentionally achieve under or over

exposure.

Reference

For details about exposure correction, see P.80.
