[QUOTE="nickt, post: 302241, member: 4923"] I think this is what Dave said. Its sort of like trying to photograph an old tube tv screen. At the right shutter speed, you get crazy results because the pictue is actually being light painted and our persistence of vision makes it all good. You get the shutter speed too fast, and you get a partial painting. I don't know for sure, but I suspect this video projector is 'painting' the picture like an old tv and you got an 'unfinished' painting. We had a talk here awhile back about fluorescent lights.
