Sharpness is more from the lens (Carl Zeiss 24-70/2.8), and also to get max DoF I set it to f/22and focussed to the near pier. It is of course tripod mounted. The image is then 3 exposures luminosity-mask blended, so there is apparent sharpness from contrast from the extra dynamic range. There is also some local sharpening in the post-processing. A lot of all this though you won't see in a small JPEG like this!!!
