z About Histogram
A histogram is the luminance distribution that shows how many
pixels of a particular brightness exist in the picture. The
histogram display of this camera shows the brightness on the
horizontal axis (left side is black, right side is white) and the
number of pixels on the vertical axis. The exposure
compensation will change the histogram accordingly. Below is
an example.
For details on pixels t page 17.
Both ends of the histogram consist only of data of 100% black or white*. Therefore, when the data is
transferred to a PC later in order to compensate it, it is impossible to restore the area that has been
blacked/whitened out. Checking the histogram allows you to know the status of the image beforehand.
* To be exact, a color image is expressed with RGB. Thus, the white is equal to R255, G255, B255, and
the black is equal to R0, G0, B0.

Use the exposure
compensation on
the positive side.
Shooting with the
exposure
compensation on the
positive side brightens
the whole picture,
making the entire
histogram shift to the
bright side (right side).
If the exposure
compensation is used
on the negative side,
the histogram will
shift to the other side.
