There are many ways to make a great picture. Sometimes, it requires you to look at a familiar subject from an unusual angle. It’s not always possible, but sometimes you get lucky.
Looks like Ryan Maxwell got a little luck and managed to take the time to put his camera on the edge of a Metro escalator. He was lucky not to have others walking up behind him to use it, for one, and luckier that it didn’t self destruct while he was there.
A long exposure from a low angle, and the escalator is transformed into something a bit more … sci-fi? Something bigger? More sinister?
