White Level eyedropper Maps the sampled tone to the setting of the White Output slider. Click an area in the Program
Monitor that you want to be the lightest value in the image. You can also click the color swatch to open the Adobe
Color Picker and select a color to define the lightest highlight in the image.
Black Input Level slider Maps the input black level to the setting of the Black Output slider. By default, the Output
black slider is set to 0, where the pixels are completely black. If you’ve adjusted the Black Output to 7.5 IRE or higher,
the darkest shadow will be mapped to that level.
Gray Input Level slider Controls the midtones and changes the intensity values of the middle range of gray tones
without dramatically altering the highlights and shadows.
White Input Level slider Maps the input white level to the setting of the White Output slider. By default, the Output
white slider is set to 255, where the pixels are completely white. If you’ve adjusted the White Output to 100 IRE or
lower, the lightest highlight will be mapped to that level.
Note: You can also adjust the Input and Output levels by scrubbing the underlined text or typing a value for Input Black
Level, Input Gray Level, Input White Level, Output Black Level, and Output White Level.

Select a color with the Adobe Color Picker
You can use the Adobe Color Picker to set target colors in some color and tonal adjustment effects. Clicking a color
swatch in an effect’s controls opens the Adobe Color Picker.
When you select a color in the Adobe Color Picker, it simultaneously displays the numeric values for HSB, RGB, HSL,
YUV, and hexadecimal numbers. This is useful for viewing how the different color modes describe a color.
In the Adobe Color Picker, you can select colors based on the HSB (hue, saturation, brightness), RGB (red, green,
blue), HSL (hue, saturation, luminance), or YUV (luminance and color difference channels) color models, or you can
specify a color based on its hexadecimal values. Selecting the Only Web Colors option configures the Adobe Color
Picker so that you can choose only from web-safe colors. The color field in the Adobe Color Picker can display color
components in HSB, RGB, HSL, or YUV color mode.
