Hi, just doing some low budget tutorial videos and wondered if there's diffusion gel substitute you could concoct. Tried wax paper but it wasn't strong enough, thanks.

diffusion is really not that expensive. Just get the real thing. You risk setting substitutes on fire if you try something that is not designed for high temp.

I second that. At $5-$7 per sheet, it would be much wiser to buy some. Plus, you'll have it for next time.

If you put the paper on frames farther from the light, to keep the heat down, something like Tracing Paper (1000H) works well for a heavier diffusion. You can also bounce the light instead.

But you could but a few sheets of diffusion gel (24"x36" I think) for maybe $5 each.

Just the other day, we threw a semi-clear plastic grocery store bag over a B-camera camera to protect it from some splattering food (it wasn't rolling during the shot, just the A-camera) and it was the most interesting diffusion effect on the video tap monitor... Sort of a Fog #10, I suppose.

Fabric softner sheets work great. Just make sure I get credit for this secret :)

For gels and diff, I get stuff from The Expendables Recycler. Not free, but it's cheaper than setting locations on fire.

Try buying a white shower curtain liner. I have used this for quite a few scenes where it's the perfect size and weight of diffusion that I need. They're less than $10 and work well. Just make sure that the curtain is far enough from your source (you'll get a softer effect this way because it fills up the frame and it won't catch fire).
