So what does a photographer do when wide awake with jet lag at 4am?
It was cold and dark, perfect to "see" in black and white, high contrast.
The street lights make for interesting shadows.
I shot with the Leica Monochrom, it seems to work well for this darker, colder feeling. 35mm lens, ISO 3200.
Did I mention it was dark? cold? lonely at 4am? Good, just the emotion I was looking for.
Pro tip: Don't try to use logic in getting up and going out at 4am, just do it and see what happens. Sometimes you just have to do it with out thinking. Right?
