 About the Histogram
The brightness histogram display shows the exposure level 
distribution and overall brightness. And the RGB histogram display 
is for checking the color saturation and gradation. The display can 
be switched with the [ 4 Histogram] menu.
[Brightness] Display
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 indicates how many 
pixels exist for each br ightness level. The more 
pixels there are toward the left, the darker the 
image. And the more pixels there are toward the 
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 
gradation in-between will be reproduced. By checking the image and 
its brightness histogram, you can s ee the exposure level inclination 
and the overall tone reproduction.
[RGB] Display
This histogram is a graph showing  the distribution of the image’s 
brightness level of each primary color (RGB or red, green, and blue). 
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 th e 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 saturat ed with no detail. By checking the 
image’s RGB histogram, you can see the color’s saturation and 
gradation condition and white balance inclination.
