Fig. 9: Water plants with reflection on the water surface and a trout. The trout was pretty close but with the fisheye dome port of the camera a fish of that size must get very close to fill the frame. One can see the forest through the water surface. — Nikon D200, Nikkor AF-S 10.5mm f/2.8 Fisheye, 2 x Sea&Sea YS-110α, Lake Fernstein, Austria, 10 August 2013 — EXIF: Nikon D200; Δt=1/91 s; f=10.5 mm; f/5.6; ISO 200; 2013-08-10 10:59:52
