Tree in the Middle of Lake
Fig. 13: This tree is about in the center of the lake and all covered with slime algae. The whole ground is covered with a fragile algae carpet. As you can see there are some spots where the carpet was recently destroyed by divers who got too close. — Nikon D200, Nikkor AF-S 10.5mm f/2.8 Fisheye, 2 x Sea & Sea YS-110α strobes, Lake Samaranger, Austria, 10 August 2013 — EXIF: Nikon D200; Δt=1/160 s; f=10.5 mm; f/4.0; ISO 200; 2013-08-10 15:52:19
