ImageDifference

This node layers images together using the Difference compositing algorithm: abs(F-B). It shows how much the

pixels differ and is useful for comparing two very similar images.

You can also specify a different compositing algorithm using the operation control.

NOTE: ImageDifference outputs the absolute value of F-B, whereas ImageMinus outputs exactly F-B. For

the standard "difference matte" situation, you want ImageDifference.

Control (UI) Default Value Function

R enabled When enabled, affect the red channel of the image.

G enabled When enabled, affect the green channel of the image.

By default, the merge is limited to the non-black areas of the

to the non-white areas of the mask.
