I just shot a project where we had a class full of kids studying and interacting within a classroom environment. We used the existing lighting within the room (panels of overhead flourescent tubes like every school i've ever been in) and blocked off the windows to cut the daylight temerature, we had a small budget,and a short timeframe.
I was talking to a pal about it who was on set but not the director on that project and he said he would have wanted it lit and shut off the overhead lights even within that budget. I said that probably the only thing I would've done is replace all the bulbs in the overhead fixtures with a brighter, colour balanced bulb, with maybe a thin diffusion on each one, and then had two kino's to add a faint bit of eyelight and backlight on the maybe 3 or 4 closeups we had, but that I would probably even do without the kino's and just leave the overhead lights as the main light and use a small reflector/icelight type eyelight on the closeups.
He seemed dissatisfied by that, and I've since talked to him twice about the same project and each time he talks about how it "should've been lit" (even though it looked great anyway, and everything that wasn't fully ideal could've been brought out in the grade).
My question is, how would you light a classroom scene if you have only a single school day (8-2:45 minus lunch and recess breaks) to shoot in the classroom?
