Highlights/Midtones/Shadows Hue Angle Controls the hue rotation in the highlights, midtones, or shadows. The
default value is 0. Negative values rotate the color wheel to the left and positive values rotate the color wheel to the
right.
Highlights/Midtones/Shadows Balance Magnitude Controls the amount of color balance correction as determined
by the Balance Angle. The adjustment can be applied to highlights, midtones, and shadows.
Highlight/Midtones/Shadows Balance Gain Adjusts brightness values by multiplication so that lighter pixels are
affected more than darker pixels. The adjustment can be applied to highlights, midtones, and shadows.
Highlights/Midtones/Shadows Balance Angle Controls the hue translation in the highlights, midtones, or shadows.
Highlights/Midtones/Shadows Saturation Adjusts the color saturation in the highlights, midtones, or shadows. The
default value is 100, which doesn’t affect the colors. Values less than 100 decrease saturation, with 0 completely
removing any color. Values greater than 100 produce more saturated colors.
Auto Black Level Raises the black levels in a clip so the darkest levels are above 7.5 IRE. A portion of the shadows is
clipped and the intermediate pixel values are redistributed proportionately. As a result, using Auto Black Level
lightens the shadows in an image.
Auto Contrast Applies both the Auto Black Level and Auto White Level simultaneously. This makes the highlights
appear darker and shadows appear lighter.
Auto White Level Lowers the white levels in a clip so the lightest levels do not exceed 100 IRE. A portion of the
highlights is clipped and the intermediate pixel values are redistributed proportionately. As a result, using Auto
White Level darkens the highlights in an image.
Black Level, Gray Level, White Level Sets the levels for darkest shadow, midtone gray, and lightest highlight using
the 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.
Input Levels The outer two Input Levels sliders map the black point and white point to the settings of the Output
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.
Input Levels slider
Output Levels Map the black point and white point input level sliders to specified values. By default, the Output
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.
Output Levels slider
Input Black, Input Gray, Input White Adjust the black point, midtone, and white point input levels for the
highlights, midtones, or shadows.
Output Black, Output White Adjust the mapped output levels for the input black and input white levels for the
highlights, midtones, or shadows.
