Ricoh R 3 manual Histogram Display

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 preventing voids and solids.

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 condition (flashing is required, the surrounding light is dark, and so on), 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.
