If you can arrange lighting perfectly in your CRT studio, you could take only the difference against the all-off state. You could extract the pixel islands' positions and composite only these smaller chunks afterward.
It could work out, but just not sure if it's worth all the hassle. It seems akin to the way you would do a stop-motion video, I suppose.
- tobr 7y agoYou would need to be in a pitch black room with only one pixel at a time lighting the scene. If you want additional light sources in the room they could be photographed and blended in with the same technique.

I think this would be a final additive pass after the pixel setup. Would also allow you to turn it off selectively... The more I think about it the more I want to try it out.
- tobr 7y agoI think you would need to get the reflections in the same pass. It’s basically ray tracing in real life: emit light from a bunch of points (screen pixels), “calculate” how they bounce through the room (ie adjust the brightness of the corresponding photo), and combine them all into a single image.
