Usingthehistogram
The histogram provides a graph that indicates the total number of pixels at each bright-
ness level, with brightnesses going from black on the left to white on the right. It is a
valuable tool for evaluating captures. A well-exposed shot usually has a full range of
levels, while under- and overexposed shots tend to show levels concentrated at the left
or right part of the scale, respectively. The histogram is only an indicator that should be
interpreted – there are many situations in which a questionable histogram will match an
exposure that is perfectly acceptable for the intended effect (and vice-versa). Look at the
histogram examples and the explanations below:
Underexposure 1
A histogram display that is concentrated on the left with few pixels elsewhere indicates
a likely underexposure. Many details will be lost in the shadows.
Even exposure 2
A histogram display that is spread across the full range indicates a likely good exposure.
There may still be a few pixels at the extremes, indicating a few spectral highlights and
saturated shadows, but this is often normal in a good exposure.
Overexposure 3
A histogram display that is concentrated on the right with few pixels elsewhere indicates
a likely overexposure. Many details will be lost in the highlights.
The Standard Preview display is the one shown
when you first turn on the camera and is
probably the view you will use most often.
It shows a preview of your most recent capture
and basic information about the settings.
Furthermore, the display enables you to
navigate the menu system and make camera
settings; see Simple description of menu items
for details.

Overexposure indicator
Although the histogram shows you when some of the pixels are
overexposed, it does not tell you which ones. In a shot with many
bright areas, it can be hard to know whether the key parts of the
image are just bright or completely overexposed. To help you find
them, the sensor unit provides an overexposure indicator, which
shows precisely which areas are at maximum brightness without
detail.
When enabled, the overexposure indicator flashes the overex-
posed pixels from white to black. To enable or disable the over-
exposure indicator, choose MAIN MENU > SETTINGS > USER
INTERFACE > Mark Overexp. or use the shortcut.
