So, generally I'm pretty decent at spec'ing out stuff for work, which is at a school. But this has sorta stumped me. So, we want to buy from projector people (not my decision). But if you find a projector elsewhere that will fit the constraints below, let me know. The projector will be used for an art history class. The classroom is rather large. The teacher wants to project it 10 feet wide (a little less ok). So width of two paintings side by side = 10 feet. Budget: $2500 or less. We can project it either from mid room (there's a hole in the furniture setup - u-shaped socratic seminar style) or from the back of the room. Mid room, about 10-15 feet away, it cannot project 10 feet wide on a screen. Someone else did a calculation and said we'd need a wide angle zoom lens with 1.0 focal point or something, whereas the projectors we found started at about 1.8-2.2. Does that sound about right? From that we concluded that the projector would need to be in the back of the room. We have an NEC LT35, which is a great little thing. We tried it in the back of the room, but the 3000 lumens was not strong enough to project strongly onto a screen at the front of the room. So we want something at least 3500, I think. The room is approximately 40ft x 30ft and has three super large windows on one side and gets a good deal of sunlight. We of course have shades. But ideally, we'd rather not have lessons in a dark room. Any ideas?
