70-210mm supertest images: gulls.

Samsung NX20, 170-190mm, ~5m focus, 100ASA, auto WB, Av mode.

As bold and habituated to humans as the gulls that hang out on Conwy quayside are, I wasn't too confident that a gull would stick around long enough to allow me to get through all 6 lenses, and my first attempt ended in the flight of the subject after 3. However this gull cooperated. Although I was concentrating focus on the eye and head, in practice this was the part of the gull that moved the most as it eyeballed me, hopped around a bit and scoped for stray chips. However focus looks ok on most of the shots. Light was right for the subject, sun judiciously cut by high cloud.
I consciously aimed for underexposure, in practice with no dark background and the gull the main point of exposure that wasn't necessary. I ended up bumping the exposure ½ to 1 eV in LR3 on all the shots. All the shots are cropped from 5472×3648 to 4800×3250, except for one of the VS1-kiron pics which is a little larger. A sail on a yacht moored in the estuary kept blowing into shot for the VS1-komine pics.
