Save and apply presets using the Adjustments panel

The Adjustments panel has a list of presets for common color and tonal adjustments. In addition, you can save and

apply presets for Levels, Curves, Exposure, Hue/Saturation, Black & White, Channel Mixer, and Selective Color. When

you save a preset, it’s added to the presets list.

• To save adjustment settings as a preset, choose the Save Preset option from the Adjustments panel menu.

• To apply an adjustment preset, click the triangle to expand the list of presets for a specific adjustment and then click

a preset. Alt-click (Windows) or Option-click (Mac OS) a triangle to expand all presets.

Color adjustment commands

You can choose from the following color adjustment commands:

Adjust Levels Auto Quickly corrects the color balance in an image. Although its name implies an automatic

adjustment, you can fine-tune how the Auto Color command behaves. See

“Remove a color cast using Auto Color” on

page 191.

Levels command Adjusts color balance by setting the pixel distribution for individual color channels. See “Adjust

color using Levels” on page 167.

Curves command Provides up to 14 control points for highlight, midtone, and shadow adjustments for individual

channels. See

“Curves overview” on page 168.

Exposure command Adjusts tonality by performing calculations in a linear color space. Exposure is primarily for use

in HDR images. See

“Adjust Exposure for HDR images” on page 178.

Vibrance command Adjusts color saturation so clipping is minimized. See “Adjust color saturation using Vibrance”

on page 175.

Photo Filter command Makes color adjustments by simulating the effects of using a Kodak Wratten or Fuji filter in

front of a camera lens. See

“Change the color balance using the Photo Filter command” on page 188.

Color Balance command Changes the overall mixture of colors in an image. See “Apply the Color Balance adjustment”

on page 188.

Hue/Saturation command Adjusts the hue, saturation, and lightness values of the entire image or of individual color

components. See

“Adjust hue and saturation” on page 172.

Match Color command Matches the color: from one photo to another photo, from one layer to another layer, and from

a selection in an image to another selection in the same image or a different image. This command also adjusts the

luminance and color range and neutralizes color casts in an image. See

“Match the color in different images” on

page 181.

Replace Color command Replaces specified colors in an image with new color values. See “Replace the color of objects

in an image” on page 184.

Selective Color command Adjusts the amount of process colors in individual color components. See “Make selective

color adjustments” on page 187.

Channel Mixer command Modifies a color channel and makes color adjustments not easily done with other color

adjustment tools. See

“Mix color channels” on page 185.
