Quite rare these days. There are three or four large common frogs in my father in law's garden pond. Quite a large pond but covered with a string mesh to keep the Heron at bay. The water snail was an extra. Camera on monopod as no room for tripod and inserted through one of several feed holes in mesh near pond edge. Some work with dodge tool but more with burn tool to reduce reflection of the net and deal with some lightening of the water surface due to light angle.
Smart sharpen. Several bubbles and pond rubbish cloned out. Auto focus with focus lock.
Bright sun, so compensation -1/3. EOS 7D with 150mm EX Sigma Macro and Sigma Ring flash used as fill. Aperture priority f14 and 1/125 sec. ISO100. Monopod helped with low shutter speed.
