Playing superheroes at Moraine Lake a couple of nights ago.
Unfortunately my superpowers do not include flying. Always make sure the shot that requires swimming is your last one of the night.
For the tech people: Canon 5D3, Canon 24mm f/1.4 at f/2.0, intervalometer, ISO 1600, 30 seconds, a splashlight pointing down to bring back the turquoise of the lake, and a headlamp on the boulder pointing up at me.
