Maybe say what the heck the film strip contains image or otherwise
perhaps? LOL
Is there something that goes wrong at the central portion of the
"projection"? Looks like a tiny collection of white spots, and could
this be related in anyway to Margus's Whisky Glass white spots?
Looks like the photons must be pretty intense to brighten that dark,
opaque-looking piece of "film".

it's my windows wallpaper texture
it's my dragon skin texture
it's my hot coals bar-b-q texture
it's my multi purpose multi spectacular red test texture
it's the attatched texture

Don't think so, the projector is very out of focus. Translate the projector
lens to <-6,0,0> and the spots are gone and the projector is in focus.
In the out of focus situation raise the density to 0.01 and the spots are
gone, or center the slide.

the film is set to "filter all 1"
