What are the materials used to diffuse the light in professional setups? Silk cloth, papers?

As a student we are being using butter papers, which i find not comfortable working with. They filter the light in a strange way, and burn quickly (i m into 1000 watt open face tungsten mainly).

What materials can one use in a zer0 budget/student level projects?

See that you can help out in some kind of pro production or rental house. Usually rental houses will give away used gels after the shoot. That's how I came by quite a large assortment of gels.

Cheers, Dave

I love Drafting Paper (1000h)... also called Tracing Paper but it is NOT super thin like you expect Tracing paper to be... it come in various sizes up to 6 foot. Great for covering windows etc... a fantastic ready available diffuser. Also great to clip on barndoors or put on a frame in front of the light source. Shower Curtain is also great but will melt if come in contact with the Lamp.

You could get some bleached muslin from a fabric store fairly cheaply.

You can use this: Posted Image

You should also be aware that you can buy all of the Lee and Roscoe filters ("the same ones the pros use" ;) ) by the sheet. They're about 53x61 cm (21x24 inches). They aren't free, but they are only $7-8 US, and a lot cheaper than buying by the roll. Its a great way to try different diffusion or colored gels. You can also check at your local grip/electric rental house. Many of them will sell you gel by the foot off of the big rolls of whatever they have in stock, and it's usually a better deal than buying by the sheet.

As David also mentioned, there are a lot of gels that get tossed at the end of big shows. Any friends that you might have (or make) in the grip and electric crafts might be able to help. Another idea would be to get your school to contact any productions shooting in your area. In the US, at least, they could get a tax credit for donating to an educational organization. The school could also consider contacting Lee or Roscoe directly to see if they offer some sort of educational discount.

What about silk cloth on a frame?


One more thing, will different lights behave differently when diffused? Like tungsten or HMI???

Silk is one of the standard diffusion materials. It's used in small frames (18x24 inches) and well up into sizes that can only be described as huge (40x40 feet and larger sometimes).

All lights will be have differently diffused. The output will be less, simply due to passing through the diff. Light to shadow transitions will be softer. Some diffusions slightly warm the light, silk does this very slightly as does bleached muslin, unbleached muslin warms the light even more.
