z Highlight Alert
When the shooting information is displayed, overexposed and clipped
highlights will blink. To obtain a better result for the blinking areas where
you want the gradation to be faithfully reproduced, set the exposure
compensation to a negative amount and shoot again.
z 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

[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.

Sample Histograms
[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.
