History of editing

In 1895 the Luminere brothers invented cinematography. Cinematography is a three in one device which allows you to record capture and project motion picture.
It was 1901 when Edwin s.porter showed that film didn't have to be one long show. He also used footage to tell a different story unrelated to what the footage originally was meant to portray.
George Mase used a tabloid effect; which is where the camera isn't moved so then it's as if you are viewing it at a theatre, so everything unfolds right infront of your eyes
D.W Griffiths realised that emotions could be portrayed through different camera angles and by changing the pace of the editing-it wasn't all down to the actors. He was credited for the narrative of a film, the production of the first American feature film and the discovery of the close up.
Griffiths created most of the editing with is now used today.

The 180 degrees rule is the theory that you can move the camera 180 degrees and the scene to still make sense if you do anymore it could make a weird illusion as if someone was taking to them selves for example.
