Caltrain, San Francisco.

Yesterday I had the pleasure of meeting Aaron Durand. I’ve been following Aaron’s beautiful photography on Tumblr for some time and discovered that he also works at Twitter. So last night we went out with my friend Nick Bilton (who introduced us and is also an awesome photographer). Aaron taught me how to take photographs of trains at night with long exposures like this one (24 seconds). It was really cool to learn something new, in a fun environment while making new friends along the way.
