The downward wing stroke looks good, and the goose nice and sharp. Good sunshine too, you must have been happy with that. I do wish the angle was not as steep, and I would apply a judiscious round of NR to the full far wing and near wing's primaries.
Hi Will, glad to hear you got that window of opportunity with the light and managed to get some snaps. Just looking at the wings, was the Exposure good, or did you have to lift things a bit, as 1600 isn't much for the 5D and there does appear to be a bit of noise creeping in on that far wing? Hope the light improves in the coming days/weeks, as a friend of mine has got a wallop of snow in Kinross.
