I took a one day photo course in August 2006 with Jeff Mullins in Tulamben. I have taken a lot of photo's on land and quite a few underwater. 

This course just gave a whole new perspective to underwater photography. I learned quite a few new features of my digital camera and also a lot about general photography. 

One advice though, do not save the money and miss the actual dive with Jeff. Then you will miss out on a really good (learning) experience. 

The only drawback - I now have to spend quite a lot of money upgrading my camera equipment!
Jeff and Dawn you are the best.
