Film camera... lol. What on earth is that???
As for playing with the exposure triangle, yes, perhaps. The issue is that no one really can say what level of irradiance is "safe" for this chip or that chip so there is a lot of guesswork. The display is not live so yes we should be able to fiddle around in post, but this is kind of unique situation where almost nothing can be locked down in terms of this pattern now, this camera move now. Its all very organic and as such it is seeming very difficult to control. Our ability to add logistical elements is unclear so while it is on the table, on camera solutions are preferable so its a less heavy lift. We also definitely cannot re-film the same paths over and over again to layer takes so no dice there.
