[Octolapse] Exposure: Flickering vs day/night brightness


Just wondering whether anybody has any tips for managing exposure brightness in long octolapse recordings.

If I use automatic exposure, I get lots of flickering, especially when printing with materials that contrast with my printbed or extruder. The extruder is dark in color, and if it's mostly in frame, the exposure automatically cranks way up. If I'm printing bright materials, the auto exposure changes as the object takes up more of the frame.

If I use manual exposure, those issues are fine, but if I print from day to night, or overnight, my timelapses end up too dark, or too bright at sunset/sunrise.

Any suggestions, other than blackout curtains? I'd love to find a way to average changes in exposure over time, but haven't found a good way so far.
