Histogram

This entry is the first on the Playback 2 menu. (See Figure 3.37.) The T2i can show either a Brightness histogram or a set of three separate red, green, and blue histograms in the full information display during picture review, or, it can show you both types of histogram in the partial information display.

The Playback 2 menu has three entries.

Brightness histograms give you information about the overall tonal values present in the image. The RGB histograms can show more advanced users valuable data about specific channels that might be "clipped" (details are lost in the shadows or highlights). This menu choice determines only how they are displayed during picture review. The amount of information displayed cycles through the following list as you repeatedly press the DISP button.

■ Image only. In this view, only the image is displayed, with no additional information.

■ Single image display. Only the image itself is shown, with basic shooting information overlaid on the photo, as you can see at upper left in Figure 3.38.

■ Histogram display. Both RGB and brightness histograms are shown, along with partial shooting information. This menu choice has no effect on the histograms shown in this display, which you can see at upper right in Figure 3.38.

■ Shooting information display. Full shooting data is shown, along with either a brightness histogram (bottom left in Figure 3.38) or RGB histogram (bottom right in Figure 3.38). The type of histogram on view in this screen is determined by the setting you make in this menu choice. Select Histogram from the Playback 2 menu and choose Brightness or RGB. You can read more about using histograms in Chapter 4.
