How do i project moving images at a low level on stage?

Hi!....i was wondering if anyone could help me out – i’m designing the set for a play in which i’d like to use a board of timber behind the actors to project simple moving images onto. i was wondering what the greatest angle on a projector could be to be able to front-project onto the surface which i would suspend only at 1.5m above stage (without projecting onto the actors)! does this require too much technology, and would it mess up the general stage lighting?....

That’s going to depend on the projector-you can research this by reviewing the technical specifications of the projector, and specifically the maximum azimuth for keystone (that’s usually the technical jargon used). You will also need to measure the ‘throw’ of the projector for that distance-usually out-of-the-box, projectors will create a fairly small image from that close of a distance, unless there are special lenses for ‘wide angle’ projection. Again, this will also be a specification that you can review, usually stating a minimum throw distance and diagonal width of the image.
Lastly, since you plan on projecting onto timber, consider the lumen count of the projector as most standard beightnesses are indicated as an image is cast onto a white screen. Your conditions, while less than optimal, may be within tolerances if the right projector is used. Also, if it’s an intimate space/stage, do research the fan noise generated by the projector you choose, and make sure you have the proper mounting hardware for it. (you wouldn’t want that tgingvto cme down on your performers!) Good Luck.
consider projecting from BEHIND the actors onto a thin white sheet.
