On this day when my kids were cycling in the park, it was a good opportunity for me to practice some panning shots of my kids cycling.
I switched my camera to shutter priority and set the shutter speed to as low as 1/5 second and started trying out the panning shot without much success. I then slowly increase the shutter speed to 1/10, 1/15, 1/20 and 1/25. Eventually out of close to 100 shots, there were only a couple of shots with reasonable result. The most suitable shutter speed for this case turned out to be around 1/20s.
Panning yields interesting result but it requires some patience and practice to achieve nice shots.
