Saturday and today I was working on an insert shoot for the last movie. Inserts are those really really close up shots - a pack of cigarettes, the face of an alarm clock, a hand reaching for something, a newspaper headline.
They're usually not shot at the same time as the main movie, and they usually don't use the actors - since all you're seeing is extreme close ups on body parts, a double will do.
The editor's usually there as well, since he or she knows what needs to be shot. They have playback of what's been cut together so far - and the playback is checked constantly, as they have to match the lighting, costumes and props so everything will cut together (although a lot of time the lighting in inserts doesn't match at all and they're counting on the fact that you - the moviegoing public - won't notice).
This time, they have the DP from the movie (running "A" camera. The "B" camera DP wasn't on the movie), the same gaffer, the same electricians and the same grips. This is a very good thing as we usually remember how we lit something - especially if we did something unusual - in Saturday's case, it was a scene in a diner where the gaffer had put a really yellow light outside the window, and the B camera DP wouldn't have been able to match it had we not been there.
Tomorrow I'm back on the TV pilot. It's supposed to rain, so it's a good thing that we're on a stage.
