I spent a night shooting around the corner of Broadway and Columbus in San Francisco a couple years ago this past November. This was my first real go at taking night shots.
This area of San Francisco is famous for neon, strip clubs and City Lights book store. Only a few blocks away is the Transamerica building - the iconic peak in the San Francisco skyline - and the surrounding financial district.
The shot above was taken with the canon 24-70mm lens at 24mm mounted on a 30d at f/14 for 2 seconds. The film speed equivalent was 100.
The three images below were all taken with the same lens at a variety of shutter speeds and apertures - all with the intention of capturing the glow of the lights that surround this corner of San Francisco.
