The histogram is a graph showing brightness levels on the horizontal axis, and the number of
pixels at each level of brightness on the vertical axis. Darker pixels are towards the left side of
the graph, and brighter pixels towards the right. By looking at a histogram you can determine
the brightness of a picture after it is recorded.
If the histogram is higher towards the dark end, set the exposure compensation (→81) towards
the plus end. If the histogram is higher
towards the light end, set the exposure
compensation towards the minus end,
then take the picture again.

High Brightness Warning

When exposure information is displayed for a picture that will be overexposed, the related

compensation towards the minus end (→81), then take the picture again.
