Displaying a histogram
A histogram is a graph showing the
brightness of an image. The horizontal axis
shows the brightness, and the vertical axis
shows the number of pixels. The graph
display indicates a dark image when
skewed to the left side, and a bright image
when skewed to the right side. The
histogram is useful to check the exposure
during recording and playback when the
screen is difficult to see.
a Set the mode switch to .
b Press to display the
histogram.
c Press MENU.
The menu appears.
d Adjust the exposure based on
the histogram.
• The histogram also appears when the
(Camera) in the menu is set to [Auto], but you
cannot adjust the exposure.
• The histogram also appears when you press
while playing back a single image
(page 35) or during Quick Review (page 24).
• The histogram does not appear in the following
cases:
– During Quick Review of an image recorded
in Exposure Bracket mode
– When using playback zoom
– When viewing and shooting movies
• appears in the following cases:
– When recording in the digital zoom range
– When the image size is [3:2]
– When rotating a still image
– When viewing Multi Burst images
• The histogram before recording represents the
histogram of the image displayed on the LCD
screen at that time. A difference occurs in the
histogram before and after you press the shutter
button. When this happens, check the histogram
while playing back a single-image or during
Quick Review.
In particular a large difference may appear in
the following cases:
– When the flash strobes
– When [PFX] (P.Effect) is set to [Solarize]
– When the shutter speed is slow or high
• The histogram may not appear for images
recorded using other cameras.

Shooting techniques
Normally, the camera automatically sets the
exposure. If the image is too dark or too
bright as shown below, we recommend that
you adjust the exposure value manually with
viewing the histogram. When shooting a
back-lit subject or a subject against a white
(e.g. snowy) background, adjust the
exposure toward the + side. When shooting a
black subject that fills the screen, adjust the
exposure toward the – side.
Appropriate exposure
Overexposed t Adjust toward –
Underexposed t Adjust toward +
