Blend Modes #

Blend Mode Description Example Image
Composite Image B is placed over Image A. Only available within the Composite Sources node. blendmodes-composite
Multiply Multiplies the values of image A and B together to produce a darker image. blendmodes-multiply
Add Adds the values of image A and B together to produce a brighter image. blendmodes-add
Subtract Subtracts the values of image B from image A to produce a new image. blendmodes-subtract
Linear Image B is placed over Image A - however the alpha values are ignored. blendmodes-linear
Max Image A and B are compared, and the maximum values are used. blendmodes-max
Min Image A and B are compared, and the minimum values are used. blendmodes-min
Screen Image A and B are inverted, multiplied together and inverted again, producing a brighter image. blendmodes-screen
Light Image A is multiplied by Image B, and then Image A is added again, resulting in a brighter image. blendmodes-light
Difference Image B is subtracted from Image A, and the absolute value is used to produce an image that highlights the differences between Image A and Image B. Only available within the Composite Sources node. blendmodes-difference
Exclusion Image A and Image B are multiplied together and then by 2, then subtracted from Image A added to Image B. The result is very similar to Difference, but with lower contrast. Only available within the Composite Sources node. blendmodes-exclusion
Dodge Image A is divided by the inverse of image B, producing an image that lightens Image A based on Image B. Only available within the Composite Sources node. blendmodes-dodge
Burn Image A is inverted, divided by image B and the result is inverted, producing an image that darkens Image A based on Image B. Only available within the Composite Sources node. blendmodes-burn
Negate Image B is subtracted from image A, subtracted from 1, and the absolute value is subtracted from 1. This is the inverse of the difference blend mode. Only available within the Composite Sources node. blendmodes-negate
