My bro-in-law paid for me to do a tour with these guys as a birthday gift. I didn't know about them but look very forward to this. The particular guide I had was Rob. Very fun, relaxed, easy-going guide and tour. It was great being able to walk alongside someone who knows photography and the city. He gave plenty of pointers, concepts to think/visualize, and reviewed my photos to see how well I was getting what he was talking about. I would highly recommend this tour to anybody, absolutely wonderful.
