Abstract
Time to get abstract! Here are some shots I did on the South St Bridge walkway in the evening. I used a 10 second exposure, my trusty 17-40 f/4L USM, and my flash set to fire on shutter close (second curtain). I set the camera's shutter to fire after 10 seconds, this way I wouldn't be touching the came and inducing shake. While the shutter was opened I slowly zoomed out for 5 seconds, then on the next exposure I zoomed in. It creates a unique effect I hope you enjoy the results.
