Cheap diffusion - painters plastic (4 replies and 2 comments)

Someone posted this tip on cinematographers mailinglist, a great resource for DP's and students. 

It's transparent plastic on a role that is used by painters to cover windows. It happens to have a nice diffusing characteristic. And it's very cheap: "about $15 a roll at Lowe’s". 

They cling to the window by themselves (static electricity). 

The plastic should not be used in close proximity of hot lamps, because they're not as fire-retardent or robust as normal diffusions. But it seems to be safe for use on windows when the lamps are at a safe distance.

It is a Sherwin Williams product: Plastique Pour Peniters 334 M2 (3600PI2) 2,74 m X121m X 7,87 (9PIx 400 PI X 0.31 MIL)

I've not used it myself yet, but I thought the tip is worth sharing. (Maybe someone has an even better tip.)

Excellent idea, it looks opaque so could be useful.
“Clingfilm” does a similar job but is much clearer also only $4.95 for 50 metres. I wrap everything in “clingfilm” tools, Camera, lenses etc when not in use. Keeps out the damp in winter. I’ve got some now on my car windows to keep the frost and snow off. Thousands of uses. Top tip, wrap bananas with it, they keep for months.

Computer error. Should read ‘They keep for weeks’ not months.

That is the kind of plastic I used on 'Shawshank Redemption' so as to blur the outside and soften my array of HMIs. The prison windows were so large that using any 'film' product would have been far too expensive.

What's nice about the plastic sheets at the hardware stores is that it comes in different thicknesses / diffusing strengths.  I had a shot in a movie where a wrecked car had been trapped in plastic and I wanted to see through it somewhat, so I picked a very light plastic.

I have been using shower curtains (frosted white).  Adding the painters plastic to my next shopping cart.

Thank you for sharing.

PS I am new to this website/forum.  Very excited to learn from all of you...
