Using the histogram

The histogram provides a graph that indicates the total number of pixels at each brightness
level, with brightnesses going from black on the left to white on the right. It is a valuable
tool for evaluating your exposure. 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.
For example:

Underexposure

A histogram that is concentrated on the left with few pixels elsewhere indicates a likely
underexposure. Many details will be lost in the shadows.

Even exposure

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

A histogram that is concentrated on the right with few pixels elsewhere indicates a likely
overexposure. Many details will be lost in the highlights

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 fine for the
intended effect (and vice-versa).

Full-details mode

In full-details mode, you can read a complete list of camera settings, plus see the histogram
and, in the background, a darkened preview of the image.
The camera-setting details are stored with the image, so you can refer to them using
FlexColor or Phocus even after you have loaded the image to your computer and stored
it in your archive.

The standard preview display is the one shown
when you first turn on the camera and is prob-
ably the view you will use most often. It features a
preview of your most recent shot and basic infor-
mation about the settings and the image itself.
Several other display modes are also available,
including histogram, capture details, full-screen
and battery saver. Please see Preview Modes for
details.
Furthermore, the display enables you to navigate
the menu system and make camera settings; see
Working with the Menus for details.
