“I don’t believe in pushing film or boosting the ISO of a digital camera except for a very occasional special look in tandem with the lighting. It doesn’t give you any more of your darkest shadows and presumably that’s what you’re after in these situations anyway. Dark scenes like these are about delicacy and it’s ruined when you whack your gamma and throw away your shadows. Not to mention inconsistent with the rest of your footage. Blocking and placement of such frail light is crucial in making it work.”
