# The quickmask thing does work with lots of steps, but it still has problems around colours and will delete all blacks not just the black from the difference blend.
Pretty sure that method wouldn't work for video though. But I swear I've heard people extracting the backgrounds from videos purely by having a static shot clear from any people/objects, as an easy alternative to green screen, so how the fuck did they do it then?

# There are add and subtract blending options hidden somewhere.
In the "apply image" and "calculations" commands. Just reading about this in the help. Might do the job somehow. Or not.

# Ahhh it's called difference masking when you do it for video, that's helped finding a lot of tutorial links.
