This was an unusual project for me. We had a lot of logistical problems in getting the subjects to san francisco so it was decided that it would be easier to shoot the people and backgrounds separately. As the timing was incredibly tight and the subjects were all over the country and world i did not have the time to shoot both. So although the big group shot is almost completely mine (four of the people were not shot by me), for the rest of the shots , i only shot the people. i hope this makes sense?
