In a sense, the ability to set up fast is MORE important with unpaid crews. The amount of time you save with real lights can't be overstated. One of the problems I've had on my short is that some people just don't show up. So once you get everyone there, the planets are in alignment, the fates are smiling, and you gotta get footage in the can. Fiddlefucking around with your homemade barn doors on you home depot lights costs you precious time, not mention that you're probably heating the set to pizza oven temps. The makeup is streaming down your actress's face, the homeless guy you found to operate one of your cameras is starting to smell like decomposing walrus. Your handsome leading man now has Broadcast News-like underarm stains. And at the end of the day, you weren't able to get critical pages shot because you just didn't have enough time. Time might not be money, but it is your movie.
Can it be done? Yes, but you better preplan and prelight the hell out of everything you plan to shoot. And no matter how much you preplan, things always seem to change.
We spend so much time here comparing Canons to REDS and whatnot, lighting is what will make you movie look like a million bucks. Not your camera.
