Photographing ice over the weekend and found this piece of ice on a small branch in the water. We tried a few shots and then noticed that adding a polarizing filter added a rainbow of colors in the ice. It might be a little overdone, but I thought it was still interesting. Sometimes you just have to experiment and try different ways to photograph your subjects. You never know what you might come up with. Canon EOS 1D MkIV with Canon 70-300mm f/4-5.6 DO lens.
