Using a Projector to project to a very close screen (stage performance)

Using a Projector to project to a very close screen (stage performance)
by

1 Answer

Answer :

Could you try doing a rear projection? Most projectors have a “mirror image” setting designed so that you can project onto a semi-transparent screen from behind and have the image appear correctly to people in front of the screen. The other standard way of doing this is to mount the projector (and maybe the screen) at a pretty high angle so that people’s shadows won’t get in the way. If you have a lighting designer for your show, he or she should also be able to help with these issues. (I’ll also make sure my fellow ask-public-ite and lighting designer friend reads this question).
