Does anyone have experience modifying lighting? I'm trying to make day and night more interesting, but I'm unsure if any of this is possible. I've spent an hour searching the API documentation and files with no success.

I'd like to reinstate gradual light toggling at dawn and dusk. The sudden switch in v16 is jarring. In addition, I'd like to heighten the transition between day and night by increasing daylight. I'm disappointed the immersive day/night cycle nearly disappears after early game. I want nightvision to remain at the same brightness level, but make daytime 30% brighter than it is now. I figured out how to modify nightvision, but can't find where to modify day...vision.

Starting with 0.16.0 darkness is supposedly controllable on a per-surface basis independently of daytime. From what i can see in the LuaSurface Documentation there are at least the following parameters:

.daytime .darkness .dusk .dawn .evening .morning .ticks_per_day .

I discovered the same values. The "darkness" field is read-only, and I don't think I can use the others to increase the difference in light levels between day and night.

game.player.surface.always_day=true
...
game.player.surface.always_day=false

Are you sure this is not just a documentation error? The 0.16.0 changelog clearly states: As the nessecity for mods to change the daytime to indirectly change darkness was a long stating cause of mod incompatibility and this was supposed to fix it. If it's not writeable that might actually be a bug.

I'll give it a try, thank you.
