How were matte paintings introduced onto the film. I've seen some behind the scenes videos of films that inserted matte paintings into frames as a background for actors to move around in without green screens. Just out of curiosity does anyone know how this was accomplished? I'm not particularly interested in trying it myself i was just wondering.
"Were" or "are"? Are you asking how it is done today digitally or how it used to be done?
If an actor crosses in front of any new background, he has to be keyed in. If they didn't shoot him against a chroma key, then they would have to create the key one frame at a time using rotoscoping (hand-drawing around the object, like keyframe animation). Once they have a key (a cut-out shape of the area crossing in front of the new background) they can paste the foreground in front of the background without it looking transparent, which is what would happen with a simple double-exposure.
However, a lot of matte paintings are added to areas of the frame where people aren't crossing in front, so simpler techniques like split-screens can be used, soft or hard-edged. Or, with some digital matte paintings, the live-action shot is scanned and just touched-up frame by frame in a computer.

I seem to recall that one or more of the glass plates survives and is exhibited at Port Arthur to show what the building was like before the roof fell in. Cinema re-writing history!
