Pixel distribution histogram

The histogram in the Exposure Adjustment tool is a graph of the distribution of pixels in the selection area. The vertical lines in the histogram show the current settings for Shadows and Highlights.

The magenta line in the histogram represents the current setting for Shadows, the darkest areas in the image.

The red line in the histogram represents the current setting for Highlights, the lightest areas in the image.

The turquoise line appears in the histogram when either eyedropper pointer is positioned over the image. It shows you where the pixels at that place in the image occur in the histogram.
