Now this is a canonical picture of Hallig Gröde. ;-)
This day, with its marvelous, quickly changing cloud formations, sun and rain delivered just the right setting. [Update] As some people in the discussion at fotocommunity.de suggested, this is a new image of the same scene, more closely cropped. Also on fotocommunity.de you can find a alternate crop of this image with a 16:9 aspect ratio.
