To display the histogram during playback

During playback you can display a histogram, a bar graph which illustrates the brightness of the displayed image so you can determine how to adjust exposure compensation. The horizontal axis of the histogram represents the brightness of the image, on a scale of 0~255 (reading from left to right), and the vertical axis measures the number of pixels for each bar. If the graph shows brightness heavily weighted on the right side of the scale (portions of the image could wash out), set exposure compensation to a minus value for a darker image. If darkness is heavily weighted on the left side of the scale (portions of the image could turn black), set exposure compensation to positive value for a brighter image.

To adjust exposure compensation while viewing the histogram

The exposure (exposure compensation, aperture, shutter speed) cannot be adjusted with the camera in the playback mode.

•With the mode dial set to P, A, S, or M, press

the monitor button to set the camera in the shooting mode. With the camera in the

shooting mode, you can adjust exposure compensation, aperture, and shutter speed.

•If the mode dial is set to playback , reset it to P, A, S, or M.

•The histogram cannot be displayed during the index display or for an image as it is stored immediately after it is taken. Please note that the histogram for an enlarged image illustrates the brightness of the entire image, not of the currently displayed part.
