Just a personal opinion, Andrew, but if a scene has movement why use a long exposure?
It can be a good technique in the correct circumstances but when you have wind movement, of foliage etc, you are bound to get blurring.
Sometimes, yes, blurring can add something but, for me, it only works occasionally. Otherwise it can appear like poor focus.
Thanks Geoff for this. The long exposure was an experiment as I had not tried it before, a successful one as it turned out as the comments it has elicited from both you and Rob have taught me a lot about this technique. I very much take your point about it looking like poor focus and I guess I have to be more careful about the setting of the shot, peripheral as well as the subject itself, (rocks instead of foliage perhaps) so thanks again for your advice.
