Topic: using a background on a scrim
Posted: 11/13/05 at 8:05am

Is it possible to light a scrim with a slide to use for a background? I would like to use the same scrim with two different backgrounds. We don't have the room for two drops. How do you do this? Is there another way without using a slide? How do you shine the light without creating shadows? I am not sure if I am clear. I would like to create a forest and then change it to a farm in the same spot. Thanks in advance for your help.

I believe the general way to do this is use a gobo. It is a metal plate that fits in front of an eliptical lense spotlight. Start here:

Rosco makes a projector that fits in a theatrical fixture that will project a full color slide. It works well on a scrim. I have seen it used many times with great results. Each slide is good for about 50 hours burn time. The slides can be printed on a color printer and then mounted in the slide blank.

The device is called the Image Pro.

Another option would be to rear project onto the scrim. This is however is constrained by space, and even more so, cost. It does allow more versatility and options.

With restricted upstage space, you can always use a mirror to reflect the image on the back of the scrim, this will increase it by up to a 5:1 ratio.
Using a Selecon Pacific Lamp, you can produce the image on acetate, from a computer nor use the Rosco Pro Image with the Pacific lamp. As the heat from the light bubble [source] is dissipated through a unique design system, reducing burn out!
Further ensure any lighting on the scrim is reduced & not at a Wash Angle.
