Multiply is a blend mode that drops out a white background while superimposing the darker portions of the image on a background.

It’s like a very fast luma key without having to make any adjustments. Here’s how it works.

In the Layers pane, stack the element with a white background on top of the background image.

Select the foreground image and go to Inspector > Properties and set Blend Mode to Multiply.

There’s nothing to adjust. Light areas are removed and darker areas are superimposed – instantly. The screen shot illustrates the process.

NOTE: The black edges in the top screen shot are from the Motion background, they are not part of the signature image itself. (The signature is Benjamin Franklin.)
