There's this about working the stupid-early* shift: normally-busy city streets are nearly deserted:
Too, the early mornings are a chance to play at art, like the images in this post. They're all snapshot with my smartphone under circumstances where it's struggling to keep up, occasionally when there's no chance at all of fumbling with any control but the simulated shutter release and there's something like a 5:1 ratio between taking photos and getting usable results. It's a form of cheating but I'm happy enough to get some image instead of nothing at all.
And, eventually, the sun rises.
* Not just a turn of phrase. Sleep deprivation and sleep-cycle upset will leave you cognitively impaired to some degree. It's possible to adapt to it, especially if you start early, something the world's militaries know in depth and detail. As do their trainees. Me, well, I'm what you call a civilian. Especially as regards sleep.
