Thanks everyone for the feedback. I guess abstract is not quite the word to describe it, but it sort of is to me because I don't do a lot of this sort of thing. For a couple of years I wrote a column in one of the racing publications here, and these were often accompanied by some of my own pictures. The paper were only ever interested in sharp images of horses featured in the edition though, so there wasn't much call for this. As for the chicken syndrome....I've shown it to people here and there and never had much positive feedback (including some of the newspaper sports photogs whose silence I took for dislike). But I've always liked it, which is why I had a mind to get opinions here.
Ed, this is a slow shutter pan....I set ISO 100 and just stopped the lens down till the shutter slowed up enough. Final exposure was 1/13 @ f10. Obviously could have used shutter priority, but seemed quicker to wind down aperture.
Thanks again, you've set my mind at rest with this one.
Cheers
Brian
Edit; more info, another shot.
