Metallic spray on dark surfaces

I heard a rumor you can project on a dark surface with a light mist of aluminum metallic spray paint. Anyone have experience with this technique?

You can project on any surface (one of the benefits of projection), but the quality may suffer.

When you are adding the metallic spray paint, you will create an uneven projection surface. It will create a speckled surface. How bad that looks depends on the evenness of your coat and the size of the pixels on the surface. The distance that your audience is from the surface will have some effect on how they perceive the quality of the image.

The dark surface will aid in contrast, especially in regards to ambient light. From what I can gather, whomever tried this first is probably trying to compensate for the loss of light back to the viewer that the surface is absorbing. Depending on how bright an image you need, either get a brighter projector or just start with a lighter colored surface and control the light that hits it.

It was an interview with the projection designer of Evan Hansen that I heard this from. He used it to project off a black background by picking up the whites off the small bits of reflective paint you can't see from a distance. We have a new projector in order that's bright enough to light an airstrip. Just seeing if that will help the image pop. I can see how the surface will get a bit gritty. Just gotta aim way upstage.

It wouldn't cost much to try it out. Paint a 4'x8' panel black and then make some 2'x2' squares with different finishes and see what works and doesn't work for what you want to do with it.

Good idea. I may try it out on a flat we have in the loft next week or so and report back. Theoretically it could be a cool effect.

That looks like something to play with for sure!

How does this differ from Rustoleum?

I mentioned this thread to a friend. turns out she was involved in the development of Rosebrand's Screen Goo. This may be the product you're looking for:
