Re: Varicam shutter speed

I think you mean to say "increase" the shutter, meaning opening it up more to let in more light. The conceit is to imitate the motion of a motion picture camera; turning the shutter "off" gives you a 1/24th of a second exposure and each frame has to much motion blur (depending of course on how much motion there is). Also, some motion picture cameras have "variable shutters" and allow you to open up of close down for effect. 220 degrees is often used to get a little more light, but in reality that only gives you less than a quarter of a stop, but maybe that's enough (?)

Also, you must consider how you're judging the exposure; typical LCD monitors exhibit a "false brightness" and computer monitors (in the edit room) have their own particular "gammas" with Apple and PC platforms being different (PC darker). The most accurate measurement is a proper waveform scope, where skin tones can be set anywhere from 40-70ire depending on effect. Personally I set my shin tones at 50-60 rather than let the highlights on the face go white when set to 70. It's really a matter of taste.
