APlayback Zoom

To zoom in on the photograph when the histogram is displayed, press X. Use the Xand Wbuttons to zoom in and out and scroll the image with the multi selector. The histogram will be updated to show only the data for the portion of the image visible in the monitor.

AHistograms

Camera histograms are intended as a guide only and may differ from those displayed in imaging applications. Some sample histograms are shown below:

If the image contains objects with a wide range of

I

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 the distribution of tones to the right, while

 

decreasing exposure compensation shifts the distribution to the left. Histograms can

 

provide a rough idea of overall exposure when bright ambient lighting makes it difficult to

 

see photographs in the monitor.
