I had the idea to try photographing icicles yesterday. So, out I went onto my grandparent's overhanging porch yesterday afternoon to see what I could come up with. Using a black piece of rubber held behind the icicle, I was able to obtain a striking black background to set off the highlights in the icicle. I used a long 30 second exposure in this image, causing the water drips to blur while the icicle stayed motionless.
