This is the swimming lake at Camp Old Indian, a Boy Scout camp where I was the Aquatics and High-Adventure Director back in the '70s. I saw this tranquil scene just before opening the swimming area one evening to about 120 young scouts. As you can imagine, the tranquil reflections would soon turn to froth as the scouts played, swam, jumped and dove.

I shot this handheld with a Canon FTb, on Kodachrome 64, a Canon 50mm lens, probably f:5.6 or 8 at 1/60th of of a sec.
