Cool light does not flatter skin tones like warm light does. If we re-gelled with CTB, we might get some frightening results. Then he had an idea. What if we just took out the bastard amber gel and left the key lights ungelled? A few minutes later, we had all the key lights ungelled, and once again, we re-balanced the video cameras. What happened next surprised me. Bob came running out of the control room as if he had just won a trip to Disneyland. “I gained a full f-stop!” he cried. Apparently f-stops are precious to video people like Bob, and he was thrilled. Why the excitement? Because video people always want more light. No matter how much light you give them, they always seem to really appreciate more.
