A very John Constable sky, Jan, I like it very much. It could be a Constable except he didn't have Rapeseed (Canola) to paint!I applaud your judicious use of HDR.
Yes I see you've got well into the HDR while I've not been looking. Again it's subtle and I like the colours - think this one's not quite as successful as the others and maybe a touch over-sharpened, but it's still a great piece of work.
A very nice shot. A scene I am familar with. I love the fact it doesn't 'look' like HDR, which shows good control of that function. A simple shot done well! THanks for sharing.
