Blend Modes
Method #
Blend Modes control how images are blended together and overlaid.
Reference Images #
These two images are the two images used for the composited examples below.
| Image Input A | Image Input B |
|---|---|
 Original ImageA straightforward RGB image. |
 Image being appliedNB: left side of the image mirrors the right, but with 50% opacity. |
Blend Modes #
| Blend Mode | Description | Example Image |
|---|---|---|
| Composite | Image B is placed over Image A. Only available within the Composite Sources node. |
|
| Multiply | Multiplies the values of image A and B together to produce a darker image. |
|
| Add | Adds the values of image A and B together to produce a brighter image. |
|
| Subtract | Subtracts the values of image B from image A to produce a new image. |
|
| Linear | Image B is placed over Image A - however the alpha values are ignored. |
|
| Max | Image A and B are compared, and the maximum values are used. |
|
| Min | Image A and B are compared, and the minimum values are used. |
|
| Screen | Image A and B are inverted, multiplied together and inverted again, producing a brighter image. |
|
| Light | Image A is multiplied by Image B, and then Image A is added again, resulting in a brighter image. |
|
| 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. |
|
| 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. |
|
| 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. |
|
| 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. |
|
| 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. |
