This experiment shows the two types of Supernova Screen material, the 23-23 high gain on the left, and the ISF-certified 08-85 wide angle on the right. Behind and above them is the matte white screen so you can see how washed out the image would be without Supernova. (The loop starts with the reference image for comparison.)
You'll note in the straight-on shot (#2) the left screen is almost twice as bright, but in shot #3, taken off to the side about 45-degrees from center, they are about the same. The 08-85 has superior off-axis viewing, but 23-23 is brighter when within 23-degrees of the projector axis. These samples are shot under the same lighting conditions as above, and are using the small Supernova One rigid screen samples we have.
