I had taken a photo a couple years before this one where I learned that railway tracks light up during the early or late part of the day when the sun hits them. I tried to get that effect with this photograph and I was happy with the result.
Long exposure at Lake Winnipeg, Manitoba. I like the way the rocks help the eye to move around the frame; the eye is drawn to the rocks, then it moves around to the clouds, then comes back to the rocks, etc. They really help "anchor" the image.
