Im doing a show in february and it calls for a bunch of projections that are really key to the show. The TD wants to use a rear projector. the screen he wants to use is fabric [not sure what kind or anything yet]. there are 3 screens right next to eachother. the middle one is going to be quite big [its where most of the action happens.]. now this set is going to be forced perspective. and a thrust stage. ive never done this before. im the SM for this show and i wanted to do a little research on the topic of the rear projector and forced perspective to help him out. what kind of rear projectors are out there and what are the best kinds. i did a google search and nothing too helpfull came up! grr.. also, what are some tips for this forced perspective thang. [its just odd to me that its in a full thrust stage.] any help is wonderfull...thanks!
