The only problem with that is that you still get a black background which you have to select and delete manually and it always seems to give crappy edges.There doesn't seem to be any way to just either delete identical pixels or select identical pixels. What the fuck photoshop?

is the quickmask thing any use or does thisspecifically need two identical layers?
the crappy edges are because a pixel is either identical or not, feathering the selection or blurring the image might help.

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.
