I have absolutely no interest in injecting politics into this forum, but I saw this article on Bernie Sanders at some big dinner, and was drawn to the projected image behind him.

For some reason I always like to look at the projection and mentally figure out where the camera was. But wait a second--it looks like the camera is to the RIGHT of the auditorium, and that the projected image is backwards. Or am I overlooking something?

Now I've made lots of mistakes in setup myself, but this one seems pretty important. If Bernie weaves left at the podium, the Big Bernie will weave right on the screen, and so forth. Ouch.
