Dagwood56, I didn't know it had its own TLA (three letter acronym)

, I just referred to them as blurs of one kind or another. I have seen them done using a tripod mounted zoom lens, a tripod mounted collared lens to give a circular pattern and both horizontal and vertical blurs using a tripod mounted camera and lens and a gimbal head. I suppose that there are so many variations on this, that if you, as the artist, like it, then that is really all that counts. Have you posted any of your work here as it would be nice to see it.
"JC" has his flower imagery very well developed, I was just trying to suggest other things that I have seen done by other photographers. I would also encourage JC to look at the underside of flowers and try photographing their sides and undersides. There are some beautiful images on the web showing this approach.
