You can use anyone of four areas in the Levels window to adjust the exposure, contrast, and color.
• The Auto button changes the exposure, contrast, and color.
• The Channel mixer, at the top, is used to change the exposure and contrast on the red, green, and blue channels.
• The black, gray, and white sliders, under the black graph, are used to adjust the exposure and contrast.
The graph is called a histogram.
The black slider controls the shadows.
The gray slider in the middle controls the contrast.
The white slider controls the highlights.
• The three eyedroppers on the right side.
The middle eyedropper, the gray-point eyedropper, is used for color correction.
The black-point and white-point eyedroppers on the ends are for adjusting the shadows and highlights.
If you make a change, and want to undo it, click the Reset button in the Levels Window.
