Extreme lush vegetation in this subarctic lake (68.5 deg N), exemplified by the inviting flowers of the White Water Lily Nymphaea candida. We could hardly navigate a boat in the vegetation-filled lake. The resident Whooper Swans loudly protested against our presence as well. I got my photos above and below the water line and felt satisfied even though my D500 on occasion drowned. Dried it out over night and it is now working perfectly again.
