I'm gaffing a short in 2 weeks, and one of the scenes is calling for an actors face to be illiuminated by a cell phone. We're trying to shoot this on the RED Scarlet, at T4, 320ISO, so I need about 64FC.
My issue is with getting enough foot candles to illuminate the face at those settings (he is strapped down to a table), and the monster that pops up just behind him (don't mind if it drops to 2.8). I'm told they also want to see the phone in the shot, that's my dilemma
To that end, I was wondering if there were anything I could build that would give me the effect I'm looking for. I've tried it with an actual flashlight app, but I lose too much once i get past just over 3/4 of a foot from the source, and the phone has to be right on top of the guy.
Any help would be very much appreciated.
