User Guide
Lowers the white levels in a clip so the lightest levels do not exceed 100 IRE. A portion of the
Auto White Level
highlights is clipped and the intermediate pixel values are redistributed proportionately. As a result, using Auto
White Level darkens the highlights in an image.
Sets the levels for darkest shadow, midtone gray, and lightest highlight using the
Black Level, Gray Level, White Level
different Eyedropper tools to sample a target color in the image or anywhere on your monitor's desktop. You can also
click the color swatch to open the Adobe Color Picker and select a color to define the black, midtone gray, and white.
The outer two Input Levels sliders map the black point and white point to the settings of the Output
Input Levels
sliders. The middle Input slider adjusts the gamma in the image. It moves the midtone and changes the intensity
values of the middle range of gray tones without dramatically altering the highlights and shadows.
Map the black point and white point input level sliders to specified values. By default, the Output
Output Levels
sliders are at level 0, where the shadows are completely black, and level 255, where the highlights are completely
white. So, in the default position for the Output sliders, moving the black input slider maps the shadow value to level
0, and moving the white point slider maps the highlight value to level 255. The remaining levels are redistributed
between levels 0 and 255. This redistribution increases the tonal range of the image, in effect increasing the overall
contrast of the image.
Adjust the black point, midtone, and white point input levels for the highlights,
Input Black, Input Gray, Input White
midtones, or shadows.
Adjust the mapped output levels for the input black and input white levels for the
Output Black, Output White
highlights, midtones, or shadows.
