I've severe sleep problems.
I live on a quite a northern latitude. Finland, but the very southern end of it. (The Arctic circle only starts about at the most northern 1/3 of Finland)
I'll upload two pictures, taken from the same spot at different times.
Which one is later, which is earlier? One is taken at 00.30 and one at 2.30. No peeking at the exif data before guessing.
Sunset or sunrise?
Couldn't tell you, as we don't really have those in the way you do.
I was wondering why it was so dark.
I used to live in. Jyväskylä. But the pictures and context you gave seem to be Uusimaa region.
I'm guessing the second one is dusk, assuming your camera didn't flip the image. Sun goes in a circle here.
The rolling blackout curtain from Ikea is what helps me a lot (I think the "fyture" one?)
Second one is pretty exactly dusk, yeah. Or 8 minutes after, technically.
The first one is dawn. Two hours apart and apparently in the same place, more or less.
And Uusimaa would fit, yeah, but I'm in Varsinais-Suomi. Same thing latitude wise though, but dawn and dusk are two minutes earlier in Helsinki than in Turku.
