In order to soften the light by creating a larger source I have decided to setup a red head about a foot from the floor, on a stand, facing upwards. the light is then bounce of a rigged large panel reflector.

1. Is this a fire hazard? i.e will the reflector burn? and if it is a possibility how do i find out if they can take the heat
2. Do you think this setup is a good idea? i don't have access to soft boxes and chimera at the moment
3. I could blast the light through a lighting net made up of silk. will this be effective at softening the light?

Your opinions are welcomed

Either a bounce board or a portable circular reflector

I've used Lastolite reflectors and poly boards for bouncing Redheads without any problems, they're usually at least a couple of feet away from the light in order to have a decent light spread from the light.

Any takes on their diffusers?

This setup is known as a "booklight".

Bounce into a 4x polycard and diffuse the light coming off the card.

This works nicely with a 12x frame (ultrabouce) and a 18k, diffused with a 12x (half grid). Have the grips contain all the unwanted spill. Get fancy and add a LCD to the diffusion frame.

Best way to tell if it is too hot: Put your hand there. Employ a layer of Heatsheild if needed. Back off the bounce if heat remains an issue,

White bounce cards are usually made with a 4'x8'x1" sheet of Foamular
http://www.filmtools.com/foamular.html

or Beadboard
http://www.filmtools...1beadboard.html

Which is then taped (using 2" white cloth tape) to a 4'x8' sheet of B/W Foamcore. (white side out)
http://www.filmtools...sss-415265.html

The side that exposes the Foamular is called the "softside" while the side that exposes the white Foamcore is called the "hardside."

This 4x8 sheet is then cut down to 4x4's, 2x4's, and 2x2's...or which ever sizes work best for you.

Sometimes we will skin the "softside" with a soft silver

Based on a DPs preferences or tendancies.

You can go to B & Q or other DIY outlets, where you can get white poly insulation boards and cut them to size.
