List of blending modes

Choose from the Mode pop-up menu in the options bar.

Note: Only the Normal, Dissolve, Darken, Multiply, Lighten, Linear Dodge (Add), Difference, Hue, Saturation, Color,

Luminosity, Lighter Color, and Darker Color blending modes are available for 32-bit images.

Normal Edits or paints each pixel to make it the result color. This is the default mode. (Normal mode is called

Threshold when you’re working with a bitmapped or indexed-color image.)

Dissolve Editsorpaintseachpixeltomakeittheresultcolor.However,theresultcolorisarandomreplacementof

the pixels with the base color or the blend color, depending on the opacity at any pixel location.

Behind Edits or paints only on the transparent part of a layer. This mode works only in layers with Lock Trans-

parency deselected and is analogous to painting on the back of transparent areas on a sheet of acetate.

Clear Edits or paints each pixel and makes it transparent. This mode is available for the Shape tools (when fill

region is selected), Paint Bucket tool , Brush tool , Pencil tool , Fill command, and Stroke command.

You must be in a layer with Lock Transparency deselected to use this mode.

Darken Looks at the color information in each channel and selects the base or blend color—whichever is darker—

as the result color. Pixels lighter than the blend color are replaced, and pixels darker than the blend color do not

change.

Multiply Looksatthecolorinformationineachchannelandmultipliesthebasecolorbytheblendcolor.Theresult

color is always a darker color. Multiplying any color with black produces black. Multiplying any color with white

leaves the color unchanged. When you’re painting with a color other than black or white, successive strokes with a

painting tool produce progressively darker colors. The effect is similar to drawing on the image with multiple

marking pens.

Color Burn Looks at the color information in each channel and darkens the base color to reflect the blend color by

increasing the contrast. Blending with white produces no change.

Linear Burn Looks at the color information in each channel and darkens the base color to reflect the blend color by

decreasing the brightness. Blending with white produces no change.

Lighten Looks at the color information in each channel and selects the base or blend color—whichever is lighter—

as the result color. Pixels darker than the blend color are replaced, and pixels lighter than the blend color do not

change.

Screen Looksateachchannel’scolorinformationandmultipliestheinverseoftheblendandbasecolors.Theresult

color is always a lighter color. Screening with black leaves the color unchanged. Screening with white produces white.

The effect is similar to projecting multiple photographic slides on top of each other.

Color Dodge Looks at the color information in each channel and brightens the base color to reflect the blend color

by decreasing the contrast. Blending with black produces no change.

Linear Dodge (Add) Looksatthecolorinformationineachchannelandbrightensthebasecolortoreflecttheblend

color by increasing the brightness. Blending with black produces no change.

Overlay Multiplies or screens the colors, depending on the base color. Patterns or colors overlay the existing pixels

while preserving the highlights and shadows of the base color. The base color is not replaced, but mixed with the

blend color to reflect the lightness or darkness of the original color.

Soft Light Darkens or lightens the colors, depending on the blend color. The effect is similar to shining a diffused

spotlight on the image. If the blend color (light source) is lighter than 50% gray, the image is lightened as if it were

dodged. If the blend color is darker than 50% gray, the image is darkened as if it were burned in. Painting with pure

black or white produces a distinctly darker or lighter area, but does not result in pure black or white.
