+MIKE AHERN I'm no expert, but what I understand of the process is that these time lapses are shot with still cameras set for long exposure times. That's how the foreground appears so bright but still manages to capture detailed night sky as well.
+MIKE AHERN Yes, what +Corey Garnett said. This isn't something you could film with traditional video. In the case of the Milky Way stuff, it looks so unusual because it's been overexposed - to the naked eye, those brightly lit mountains were probably incredibly dark. The light is only pulled out of them (and the stars) through a long exposure. It wasn't an easy thing to film this well, I'm sure.
