La photographie

The choice of sensitivity (ISO - 800) was dictated by the poor lighting at the time of the shooting. This sensitivity leads to some granulosité of the image. The opening (f/13) allows sufficient depth of field. By shake blur is avoided with the choice of speed (1 / 400). It would be interesting to take this picture, in sunny weather, with ISO - 100, use of tripod, f/16 and speed determined by these parameters.
