I created this interesting river rapid abstract during my recent Banff National Park photography tour. It was damn cold that morning at the Columbia Icefields. There was a fresh dusting of snow on the ground and the rocks near this river were covered in ice. The sunrise was non-eventful, but about the time that one of my clients (from LA) felt that he was freezing to death and went back to the car to turn on the heater, the sun came up over the mountains at a very low angle which back-lit this small river. The boulder shadows and white water were too much for me to resist, so I pulled my camera back out and explored the simple beauty of the rapids, water, and splashes with my 70-200mm f2.8 IS lens. Normally, I would have used an exposure of 1/2 second or longer to render the water silky smooth, but I wanted to capture the random splashes as they burst above the river so I used a shorter exposure of about 1/4 second.
