Viewing Multiple Images: Thumbnail Playback
To display images in “contact sheets” of four or nine images, press
the button in full-frame playback. The following operations can
be performed while thumbnails are displayed:
Highlights are the brightest portions of the image. Details may be
lost (“washed out”) in areas of highlights that are overexposed. Use
highlights as a guide when setting exposure.

4 Frame number/total number of images
A histogram is a graph showing the distribution of tones in the
image. The horizontal axis corresponds to pixel brightness, with
dark pixels at the left and bright pixels at the right. The vertical axis
shows the number of pixels of each brightness in the image. Note
that camera histograms are intended as a guide only and may differ
from those displayed in imaging applications.

4 Histogram
Some sample histograms are shown below:
• If the image contains objects with a wide range of brightnesses,
the distribution of tones will be relatively even.
• If the image is dark, tone distribution will be shifted to the left.
• If the image is bright, tone distribution will be shifted to the right.
Increasing exposure compensation shifts tone distribution to the right. Tone distribution shifts to the
left when exposure compensation is decreased. If bright ambient lighting makes it difficult to see the
display in the monitor, the histogram can be used to get an idea of overall exposure.
