The fact that traditionally silver screens were used makes me wonder if they really could be an option were it not for the hotspotting issue. My projector is mounted on the floor, so in my mind with a silver screen there is no problem with hotspotting because the angle of incidence is such that to see the hotspots of the tubes I'd have to be standing on my couch - correct? Anyway if this is the case what do people think of the character or quality of the image produced by a silver screen. Any issues here?
I have been experimenting with making my own paint lately with artist's acrylic binder and magnesium carbonate. I am going to paint the back of the screen with silver to reflect any light that gets through the slightly translucent MgCO3 and canvas screen so that it goes back out to the viewer. Because I will use silver anyway on the back of my screen I'll probably try to project onto this as a first surface too as an experiment. I was wondering if anyone else has had experiences with silver surfaces.
I'm assuming that there is a good reason why the silver is not generally used except in curved screens. Is it because in most applications there would be hotspotting issues, or are there others?
