Dusty rooms

For my next project I'd like to have a dusty room. Dusty as in rays of light coming through the window reflect off particles of dust hanging in the air. As the location in question is not particularly dusty, I need some advice as to what type of substance I can scatter in the air to get this effect. It must be as light as possible so it will have a lot of "hang time".

Thanks

Blendered paper? As in putting sheets of paper inside a blender? Interesting, will give it a try.

well I cant believe that I sounded so much convinced but it was really a brain storming. But it will work I guess. You just should make sure that the paper is low quality or old. maybe some old quality toilet paper or old newspapers.

I use carpet cleaning powder. It makes the room smell nice as a side effect.

Can't you use a smoke machine and wave the smoke evenly in the air? They did that on a featue where I was an extra.

using shredded paper cut down to fine dust particles?! have fun cleaning that up...

definately use a smoke machine, and have someone fan it out as it comes out.

You can get smoke machines for about $20 at Wal-Mart right now, that would be the way to go.

Sorry but no WalMart in Portugal! I'm afraid a smoke machine would put out too much smoke, considering this room is only 4 x 3 meters. I will figure something out, thanks for the help.

I've used a smoke machine to do a light haze in a fairly small room. Just spray it infrequently and fan it. That's how it's done on most productions.

If there's no Wal-Mart, they can be purchased for a similar price online.

back light

Whatever dust particle source you find make sure you use a decent back light

Good luck

Absolutely right about the back light. Here's a thought......Dirt. I had to get this same effect once. Get a rug, like a door mat with thick carpet. Get it as dirty as possible. As you are rolling camera shake it from above and from one side of the frame. Have a small fan behind you from a distance. This worked for me. You just have to be careful and not shake it too much. It looks so fake it's comical if you do. Good Luck......

i have had todo this before. I just took a low wattage fog machine $20 bucks from somewhwere and then took toilet paper and tore it above the camera to give the haze a more particle-like dust. It worked really well.
