* A12 appears even when “No Info” is selected, but disappears if no
operation is performed for two seconds. When no operation is
performed for two seconds in “Normal Display” or “His Info”,
only “Edit” disappears.
A guide indication for each available button/key operation appears as
follows on the display during operation.
A histogram shows the
brightness distribution of an
image. The horizontal axis
represents brightness (dark at
the left and bright at the right)
and the vertical axis represents
the number of pixels.
The shape of the histogram
before and after shooting tells
you whether the brightness and
contrast are correct or not, and lets you decide if you need to adjust the
exposure and take a picture again.
