Started diving in 1946 with hard hat, scuba in 1967. But Underwater photography in 2010, first camera was an Olympus, I forget the model in an Ikelite housing, then several more until now I use a Nikon D7200 and a D500 in Subal housings.
Retired, live in Los Angeles, prefer macro photography and am still learning, every trip a little more. My favorite activity is making friends in the countries I visit, such as the Philippines and Sulawesi, Indonesia. Favorite resorts are Club Ocellaris in Anilao and YosDive in Lembeh.
