About the camera UNFINISHED.

A few months ago I worked on The Sweeneys as a supporting artist however I watched the camera men closely and how they used the camera and the amount of times they did the scene over and over again which helped me to understand that having a few copies of the same scene isn't a bad thing because the actors or something in the shot can lead to continuity errors and the black and white timecode clapper board is useful at first I didn't know why directors use it but it's useful because when you're editing you can see the different takes and you can choose which ones to take out and which ones to keep, we don't have one but we can easily use a piece of paper and just simply write take one, take two and so on..
