NOTE

• You can use key customization to configure the [W] and [X]

buttons so they control the EV shift setting. Then you can

perform EV shift while viewing the results on the on-screen

histogram (page 138).

How to Use the 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. If

the histogram appears too lopsided for some reason, you can

use EV shift to move it left or right in order to achieve better

balance. Optimum exposure can be achieved by EV shifting so

the graph is as close to the center as possible. For snapshots,

you can even display individual histograms for R (red), G

(green), and B (blue). These lines can be used to determine

whether there is too much or too little of each of the color

components in an image.

Example Histograms

A histogram towards the left side

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, as shown in

the nearby image.
