I'm a little late getting started on this one, but it sure is fun! I played around with some different methods today and I'll share some of them here. This one is obviously a zoom blur of some Alyssum in one of my wife's lovely gardens. Used a tripod to keep the blur lines (more or less) straight. :D
50D, EF 70-200 f/2.8
f/11 @ 1/10, ISO 100
EXIF says 180mm but that was just where I started
Hi Kerry !!! Good move keeping on a tripod ... for the next try setting the shutter speed to one second then trip shutter wait a bit then zoom !!! Will have the center sort of in focus and not blurred !!! Neat !!!
