I have been diving for 20 years and have always been interested in underwater photography, but just recently got a so called "semi-professional" camera (D300) and Seacam housing. My first photo dive was during my "Advanced Open Water" class in the mid-90s using a Motor Marine 2 camera, but then I didn't take any underwater pictures until about 5 years ago when I got a Panasonic LX3 with 10Bar housing. (some photos from this camera can be seen here: http://florida.scubasoft.net/#1.22 )
I live in Florida and primarily shoot pictures in caves. Hopefully I can learn a thing or two on this forum.
