Does anyone here use the zebra lines set at 75 to set exposure on someone's face? One time I was taught by a camera man at FOX to set and use Zebra at 75 and when you see small blotches of zebra on the high cheeks and forehead... you know you're exposure is spot on.
Problem is, I vaguely remember the precise amount of Zebra that was present on the face when he showed me. Does anyone use this technique? And if so, do you have a guideline as to how much zebra you like to see on the face to know exposure is spot on?
