Hi,
I am trying to setup a projector system for my church. We have a stage and I am planing on using the projector to create the backdrop of the stage. I have found a projector, BenQ MP776 ST, and need to mount it 16' from the screen. This has to be the measurement because the ceiling is too high (30') at all other locations. With this throw distance I get the screen size I want (~27' x ~15'), but I still have to mount the projector to get an accurate dimension measurement.
The problem I have with my stage is that it is not always dark and there are times when the stage lights are on. Based on preliminary testing I can see that the backdrop image will be dark enough with the lights off, but needs a higher screen gain (I think) to get a darker image with the lights on. I can not afford a real projector screen and need help with a DIY screen. I want to create a framed projector screen, but do not know what to do.
Here are some of my questions/suggestions:
1. Highest gain DIY screen as possible. I think I will need this to produce an image with the lights on. Please advise me and let me know if this is not the case.
2. It has to be painted? I think this produces the highest gain, but do not know if there are other high gain materials.
3. Screen cannot be too heavy. I am thinking about using sheet rock to produce the screen, but am concerned due to the weight. I could use a blackout cloth, but it is expensive and there would probably be seams. I dont know what the cheapest material to use is for a screen that will probably get painted. Could I use bed sheets since I have those readily available? Please let me know what the cheapest way to create the big screen. Note: I would not mind seams if it meant a cheaper cost of production.
4. Also, Grey vs White?
Please help me figure out how to make the screen.
