On the menu’s [xHistogram] setting, you can select [Brightness] or [RGB]. (p.35)

Sample Histograms

This histogram is a graph showing the distribution of

 

the image’s brightness level. The horizontal axis

 

indicates the brightness level (darker on the left and

 

brighter on the right), while the vertical axis

Dark image

indicates how many pixels exist for each brightness

 

level.

 

The more pixels there are toward the left, the darker

 

the image. And the more pixels there are toward the

Normal image

right, the brighter the image.

 

If there are too many pixels on the left, the shadow

 

detail will be lost. And if there are too many pixels

 

on the right, the highlight detail will be lost. The

Bright image

tones in-between will be reproduced.

 

By checking the image’s brightness histogram, you can see the exposure level bias and the overall tone reproduction condition.

[RGB] Display

This histogram is a graph showing the distribution of the image’s brightness level of each primary color (RGB or red, blue, and green). The horizontal axis indicates the color’s brightness level (darker on the left and brighter on the right), while the vertical axis indicates how many pixels exist for each color brightness level. The more pixels there are toward the left, the darker and less prominent the color. And the more pixels there are toward the right, the brighter and denser the color. If there are too many pixels on the left, the respective color information will be lacking. And if there are too many pixels on the right, the color will be too saturated with no detail.

By checking the image’s RGB histogram, you can see the color’s saturation and gradation condition and white balance bias.
