This was a surprise rainbow that I saw while driving up to Lake Winnipeg for photos. It was actually a double rainbow and you could see the entire arches. This was a bit later as it began to disappear, but I like the effect of just a small portion remaining in the sky.
Prior to getting an infrared converted camera I was using a filter that I would screw onto the lens of my regular camera. Doing it this way caused exposures to be about 20 to 30 seconds long. Hence the streaking clouds. It worked out well as they became an important part of the image.
This photo isn't technically abstract, but the shape formed by the melted snow certainly is. This was shot near Churchill, Manitoba, on the way to viewing polar bears.
