And it does make me wonder if they ever shut off all the lights on the space station and just sit up there in the dark.

Yeah, I think they have to in the cupola, which is, I think, six windows and then a single... hexagonal window, that they can actually be in.

When they go to take photos of the Earth, that has to be pitch black because you don't want light reflecting off the windows into the cameras.

That makes sense.

And they use regular DSLR cameras.

And what they do is, I think they've got this felt thing these felt sheets with Velcro on the ends and they can make a little tent below the cupola.

Uh, cause I think the cupola also functions.

Yeah.
