Well I went out this weekend and tried to get an action shot of my Bird. You know, using a fairly slow shutter speed and panning with the car as it goes by at 30 mph?
It's tough to do! The background is blurry (good) but the car is a little blurry too. I would expect the wheels to be blurry but hopefully not the rest of the car (which it is.) It sounds like I'll have to practice-up and take about 30 pics to get one good one.
