B: Shooting Information Display
258
Highlight Alert
When the shooting information is displayed, any overexposed areas of the
image will blink. To obtain more image detail in the overexposed 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 [x2: xHistogram
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.
