Considering the interest in this thread, I think it would be great to be able to share the results more widely. It would be great if you'd be okay with posting the results of your processing here, or in a similar thread, and we can get our heads together for some collective wisdom. Perhaps a watermark of "photos by / processing by" wouldn't be a bad idea, just in case they escape into the wild and someone wants to offer us fabulous jobs as guest lecturers somewhere, but I'm not otherwise worried about attribution or public/private display. I do appreciate the compliment and consideration, though.

(To paraphrase one of my favourite What The Duck cartoons, the best way I've found to stop people from stealing my photos is to keep taking the kind of photos that I do.)
