I try to take pictures as often as I can, but usually I get so distracted that I forget I've got the camera with me!
We use a Canon PowerShot S70, and an underwater housing (I can't think of the brand/ model).
Most of my pics are on my work computer, but here's a few from this summer, and one from October when we were doing our underwater pumpkin carving contest. That's my friend Michelle with her pumpkin
The water visibility/ clarity was not great for any of these pictures, so sorry about the quality.
