Okay, I appreciate the input that I've gotten and after thinking about it overnight I've withdrawn my objection to edited photos. What do you think about this? I'll ask entrants on a voluntary basis to briefly describe any outside-the-camera editing that was done on the photos. This will enable us to learn from each other. Case in point - I had never heard of HDR photos. I will also create a new "Best unedited photo" category for those that weren't edited.
