My director decided 2 weeks before the run of our show that he wants to use rear projection instead of a number of cloth drops. Sounds great, except he put me in charge of it! I have not the slightest clue what I'm doing so I turn to you all for help. Heres my list of questions..answer as many or as few as you care to. But first a little background about the venue/scenario. *20x30 Screen *15 foot throw (yikes) *No existing projector (At least not that will do what we need it to.) *Size of screen can be "shuttered" with borders and traveler if need be. Ok, now questions: *If the screen is 20x30, what aspect ratio is that? *I am hoping to have a 16:9 aspect ratio in the end so what dimensions do I need to make the screen in order to accomplish that? *Can anyone reccomend a good projector and lens that will suit my needs? I've used several different lens calculators but it is just confusing me more. *Would you suggest using a slideshow program (PowerPoint) or a program such as Sound Cue System 10 with built in video cues (Here)? *Does anyone have any experience with the program Keystroke from Rosco(Here)? I'm sure I will have more and more questions as we get closer to the show. Thanks so much for your help, CB never lets me down!!
