I went to South Texas for the birds, but this Leopard Frog was a nice surprise.

I took this photograph in early April at the Laguna Seca Ranch in the Rio Grande Valley of South Texas. While the primary objective of my trip was to photograph some of the birds that are found nowhere else in North America except in South Texas, when the bird activity waned, the Leopard Frogs and several species of snakes made good stand-ins.

Using a 500mm lens with a 2X teleconverter to photograph a subject at the minimum focus distance of 15 feet results in a vanishingly small depth of field. For this shot I stopped down two f-stops from the maximum aperture to increase the DOF to a still-tiny 0.2 inches.
