Slow Down Boston I - Originally uploaded on flickr by stevegarfield.
To get this shot, I followed these instructions from Glenn at BostonNOW:
With slow shutter try some panning with moving objects.Fun.
Shutter about 15th sec. Lens greater than 50mm is best. Have subject moving from left to right (or right to left). You stay stationary and pivot your body with the subject. Snap shutter in middle of "twist".
