This is the third day I've tried this outdoors and the only one I've partly liked. Found it difficult to shoot the slower speeds without blur (my movement most likely) but did find that I could do it better when kneeling down this morning - almost as well as the seated attempts indoors. All in all, a fun exercise.
I don't understand anything you're talking about it's way above my pay grade but I do like your photo! Love the frost around the edges and the beautiful red, brown and golden colors.
Prefer the centre shot. Can't quite work out why it is brighter. So many variations in aperture and ISO as well. Looks like a technique that demands a tripod 8-)
