 AF Point Display
When [33: AF point disp.] is set to [Enable], the AF point that has
achieved focus will be displayed in red. If automatic AF point selection
is set, multiple AF points may be displayed at the same time.
 Histogram
The brightness histogram shows the exposure level distribution and
overall brightness. The RGB histogram is for checking the color
saturation and gradation. The display can be switched with [33:
Histogram disp].
[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
brightness level. The more pixels there are
toward the left, the darker the image. 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. 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 the 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. 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. If there are too many pixels on the right,
the color will be too saturated with no gradation. By checking the
image’s RGB histogram, you can see the color’s saturation and
gradation condition, as well as white balance inclination.
