Day 84: This was the second time I've attempted the panning technique. Quite honestly, I think I had better results my first time around. I used a longer focal length this time, so this may have had some bearing on my results. Anyway, this was my best shot of the dozen or so attempts I made during this session. With this shot, I converted to B&W and tilted the subject in an attempt to give the illusion of more speed. I estimate the car was going about 40 mph (64 kph).
