I can't quite remember this conversation, but I think this is pretty close:

At the Seattle Robotic Society's Robothon event I was talking to the builder of the winner of the Robo-Magellan competition. This involved an autonomous robot covering rough ground outdoors to a goal. He mentioned that he finally had to put a filter over his CMU cam to make it work properly. Here is the part my memory fades on. I THINK he said that the camera was being oversaturated by UV light, and that adding a *framistat* level UV filter, it worked much better. Unfortunately I don't remember his name or the nature of the filter. One of our mentors is a SRS regular, I'll ask him if he knows how to find this out.

Sorry I couldn't be of more help.
