Diffusing light the easy way.

Caught... Making do with some curtain material and an already erected,
soft box!

Quite a few of the better softbox designs use two layers of diffusion
material, with the inner one a couple of inches behind the front surface.
The Bowens/Regester Wafer is a good example.

Yep! Not all whites are really white. This is especially true in paper and
plastics. Setting a manual WB can get you close if there aren't any oddball
properties to the diffusing material.
I can see them as being a really nice super large softbox. Have you found
any great variances in color between them? Was it detrimental? I'm sure
variances in thickness can also change color. It probably doesn'y matter
much for film?

Pretty old hat. Gotta watch coloration from the fabrics.
In the winter here people put up these god-awful looking temporary
garages over their driveways to avoid snow clearing. (illegal in my
snobby town). Their only redeeming feature is the delicious light inside...

About 30 years ago I used some "fiberglass" Curtain lining as a back
drop with a slave flash behind it. All the current Chinese diffusers and
soft boxes use a sort of course curtain material so I can't see how it
wouldn't be correct.
The pic I pointed to has no shadows behind the children, despite them
being almost against the wall. I guess the 2, 1000 watt floodlights
above the tent did their job!

Re: diffusing light the easy way.

I was looking into this once & chatted with an interior designer... the
way to get the most diffuse lighting is with two layers of thin white
curtains. I can't explain the science but apparently it just spreads
light around more softly. I don't know if this technique has been used
for studio lighting or perhaps this guy was not correct. Maybe someone
else can comment?
