Practice, as in regularly, no. But I gave it a try last fall, with my daughter on the swings.





Rebel T1i, EF-S 17-55mm f/2.8 IS USM, zooming during exposure, f/22, 1/20s, ISO100, handheld


This was about 3 weeks after I got my first dSLR; I needed a slightly longer exposure but it was too bright out - I later purchased a couple of B+W ND filters (#103/0.9 and #110/3.0) to take care of that problem.


If you have a zoom lens, just go try it!
