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 145). ■ 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. A histogram towards the right side 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, as shown in the nearby image. 143 ADVANCED SETTINGS
