Peyto Lake is located 40 km north of Lake Louise along the Icefields Parkway (Highway 93N) in Banff National Park.
This image is an HDR composite using Photomatix Pro. Three separate exposures (1/5, 1/15, 1/50 at f/8) were combined. Camera was set to ISO 100. A Singh-Ray 2 stop ND Grad filter was also used to help control the brightness difference between the sunlit mountain and the valley bottom still in shade.
Winter sets in as ice forms on the surface of Peyto Lake. Sunlight from the rising sun slowly sweeps down the side of the mountains.
