Choosing among them is really choosing two things: where you sit on the curve from deepest contrast to highest brightness, and whether you need sound to pass through the screen or an image to float.
One grade tells you where a surface sits. The higher the number, the deeper the black and the more light the surface absorbs, and the more projector power it asks for. The lower the number, the more image brightness it returns.
1.0 would be theoretical true black: a surface that returns nothing, the image included. 0.8 is the deepest surface we build today; 0.4 is the brightest.
One part of this runs against intuition. A lit space wants a darker surface, not a brighter one. A low grade returns more of the image, but it returns the light in the space in the same measure, so it is the first to wash out. Pair a deep grade with a powerful projector and the picture stays legible with the lights up. Reach for a light grade when the projector runs short against the size of the picture, and keep that space dark.
These are the grades we keep standing. But the curve is continuous, and so is the work. Ask for a value between two stops, or push past our deepest stop, and you’ve named a Cluster: a surface forged to order, for the one scenario nothing standing quite meets.
* A Cluster is developed for your scenario: a dedicated run, a longer road, and a higher cost. It is how we hold a surface for every scenario, including the ones no one has needed yet.

Transparent Scrim is a partly transparent optical surface for floating images, reveals, and apparitions. The picture appears to hang in space, then vanishes. As a continuous woven surface it forms to the shape of the reveal, and it takes both front and rear projection. For the cleanest result, rear projection with an ultra-short-throw lens keeps the beam out of the audience’s eyes and the spill light off whatever sits behind the screen.
