OTHER RECORDING FUNCTIONS

Using the Histogram

You can use the [DISP] button to display a histogram on the monitor screen. The histogram lets you check exposure conditions as you record images (page 25). You can also display the histogram of a recorded image in the PLAY mode.

Histogram

A histogram is a graph that represents the lightness of an image in terms of the number of pixels. The vertical axis indicates the number of pixels, while the horizontal axis indicates lightness. You can use the histogram to determine whether an image includes the shadowing (left side), mid tones (center), and highlighting (right) required to bring out sufficient image detail. If the histogram appears too lopsided for some reason, you can use EV shift (exposure compensation) to move it left or right in order to achieve better balance. Optimum exposure can be achieved by correcting exposure so the graph is as close to the center as possible.

•When the histogram is too far to the left, it means that there are too many dark pixels.

This type of histogram results when the overall image is dark. A histogram that is too far to the left may result in “black out” of the dark areas of an image.

•When the histogram is too far to the right, it means that there are too many light pixels.

This type of histogram results when the overall image is light. A histogram that is too far to the right may result in “white out” of the light areas of an image.

•A centered histogram indicates that there is good distribution of light pixels and dark pixels. This type of histogram results when the overall image is at optimal lightness.
