On the forum I regularly visit, Pentaxforums.com, there's a weekly challenge with an always changing subject. This week, the challenge is to make an abstract photograph. I like abstract photography, because it challenges my creativity. I've shown my soap bubble series on this blog before, and I experimented with water drops on the back of a cd before. I decided to do a similar thing again, so I played with water and a cd today. Here are some of the results, more can be seen in the gallery on my website.
