Is there a way to export all lighting as a separate layer?

Hi, really new to this. Just curious, is there a way to export lighting as it's own, seperate .png layer?

I want to have two .pngs: one of the figure/background, and one of the lighting layer which can go above the background. Of course, when I remove objects or set them as non-visible, the lighting on them also disappears. Was wondering if there's a workaround?

    Using Canvases from the Advanced tab of Render settings should enable what you want, using Light path expressions (LPEs).

    Thanks! Do you know where documentation on how to use canvases are? I've never played around with the advanced render settings.

    I don't have a link to hand, but nVidia has/had some discussion of Light Path Expressions in a blog.
