Highlight Alert
When the shooting information is displayed, any overexposed areas
of the image will blink. To obtain more image detail in the
overexposed, blinking areas, set the exposure compensation to a
negative amount and shoot again.
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.
[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.
