About the Camera Raw histogram
The histogram in the upper right corner of the Camera Raw dialog box simultaneously shows
the red, green, and blue channels of the selected image, and updates interactively as you
adjust settings. As you move any tool over the preview image, the RGB values for the area
under the pointer appear below the histogram. Selecting the top left or right square indicates
where on the image current settings are clipping (losing details) in the shadows or highlights,
respectively.
