When I'm not working at my day job, I spend much of my time traveling on buses and trains. Getting from here to there, walking and taking photos. Then I Get back on a bus or a train, going somewhere else, often deciding where to go on the way there.
I normally work on photos while in transit, or, for example, on a street corner in Times Square. Or Bushwick. Wherever. That's one of the beauties of having a smartphone. I take the photos and edit on the go.
