Adjust shadows and brightness using Levels
1 Do one of the following:
• Choose Enhance > Adjust Lighting > Levels.
• Choose Layer > New Adjustment Layer > Levels, or open an existing Levels adjustment layer.
2 Choose RGB from the Channel menu. When set to RGB, your adjustment affects all three (red, green, and blue)
channels. If you are working on a grayscale image, it will only have the gray channel.
3 Set the shadow and highlight values by dragging the black and white Input Levels sliders (the left and right sliders
directly under the histogram) to the edge of the first group of pixels on either end of the histogram. You can also
enter values directly into the first and third Input Levels text boxes.
