consistency of lighting, match

With film and video it is important that scenes used together match in Mood and spirit. This can be challenging when parts of a sequence are shot days - or sometimes months - apart, or when exterior light changes in mid-sequence. Also, the relative brightness of the subject, walls, and any windows should be constant unless the angle changes drastically. Quote: I have the assistant keep a shot-to-shot logbook which gives the f-stop, the filtration, whether there were any [camera] nets, the focal length of the lens, etc. . . . [in case] you have to come back and finish it three weeks later but you want everything to match. - John Bailey [ML]
