About the Histogram
The histogram is a graph that allows you to judge the brightness of the recorded
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 dark,
adjust the exposure compensation to a positive number. Similarly, adjust the
exposure compensation to a negative number if the image is bright (p. 73).
Overexposure Warning
In detailed display mode, overexposed portions of the image flash. You can use the
histogram as a guide to set the exposure compensation to a negative setting and
retake the image.
The following information may also appear with some image files.

Notice Concerning Shooting
When using this camera to shoot scenes containing extremely bright subjects, a
vertical, red bar of light may appear on the LCD monitor. It will not be recorded
when shooting still photos, but will be recorded when shooting movies. This is a
normal occurrence in devices containing CCDs and does not consitute a
malfunction.
