Anyone know of a rear lit green screen material?
Try taking a silk and lighting it using a green gelled soft light.

These guys want to shoot day for night in an apartment.
There are four 3x6 windows along a far wall that the
director want to put a city scape on later. However,
the room itself needs to feel dark. The solutions I
came up with was to either find a backlit green screen
material or a translight. However, I think they've ruled
out a translight. I guess I could gel the windows green
and then silk it. But it definetly worries me since I can't
do a test first.
Anyone else heard of back lit green screen material?

It's a huge loft and I'll be hand held behind a character hiding in the shadows. He watches the other guy walk across the space from left
to right and into the kitchen. The apartment is supposed to be very dark and high contrast. I worried that with all of the lighter colored set dressing introducing those other units would really ruin the mood or that the guy will cross the lights as he walks.
I'll try to post a picture of the space later today.

Why not use a back lit blue screen because it seems more likely that blue light would be coming through the window at night rather than green.
But any color spill would cause a problem for keying.
Chris: The green screen doesn't have to be lit to "key" level; in fact quite a bit underexposed is actually okay. It just depends how dark you want the walls to be. Sometimes the ambient light on set is enough.
You would probably have just as much trouble keeping a backlit greenscreen the proper level, as the outside daylight level changes throughout the day.
