Cloisters Lady Soft Edit

A chance encounter. I asked if I might take her photograph. She did not object. She wondered if the picture would be improved by some sweeping action. Of course she was right. This was easily the best of the three photographs I made of her. How wonderful it is when strangers agree to be photographed.
Nikon D2Xs + Sigma 15-30mm f/3.5-4.5 lens.
Typical for many ultra wide-angle lenses the Sigma AF 15-30mm EX suffers from very heavy barrel distortion at the wide end of the zoom range. The situation eases continuously towards the 30mm where the lens is almost free of distortion. This photograph was taken at 22mm. Distortion was very noticeable and difficult to correct in post processing.
