Basic Functions
While a recorded image is displayed on
the LCD monitor, you can check the
exposure with the graph (see About the
Histogram (below)) that shows the
distribution of the brightness data. If the
exposure requires adjustment, set the
exposure compensation and re-shoot.
(Press the DISP. button if the histogram
and other information is not shown.)
Please note that image information
recorded by this camera may not display
correctly on other cameras and image

About the Histogram
The histogram is a graph that allows you
to judge the brightness of the shot
image. The greater the bias toward the
left in the graph, the darker the image.
The greater the bias toward to the right,
the brighter the image. If the image is
too dark, adjust the exposure
compensation to a positive value.
Similarly, adjust the exposure
32
compensation to a negative value if the
image is too bright (p. 80).
