About the Histogram
The brightness histogram display shows the exposure level
distribution and overall brightness. The RGB histogram display is for
checking the color saturation and gradation. The display can be
switched with the [4 Histogram] menu option.
[Brightness] Display
This histogram is a graph showing the distribution of
the image’s brightness level. The horizontal axis
indicates the bright
ness level (darker on the left
and brighter on the right), while the vertical axis
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 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 see t
he exposure level inclination and
the overall gradation
[RGB] Display
This histogram is a graph showing the distribution of each primary
color’s brightness level in the image (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 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 inclination.
