Hello: Dan here. Just signing in to Wetpixel for some interesting content reading.
I am into the underwater world for 42 years now in 2016. I've done some commercial diving when I was younger, reintroduced to sport diving in the late 80's, have done quite a bit of shipwreck diving in the Great Lakes and produced several videos about them. Then I had another lapse but I'm jumping back in again.
