That was pretty cool and I can't imagine how hard that was to pull off. There was a 360 pinhole shot of a music video recently done on film too which did have a making of video and that was crazy.
I have never poured a wet or dry plate, but it seemed like there were lots of defects in the final images that flickered past my screen. Was that normal in the past? And only the best plates were shown to the customer and the others discarded?
