I was shooting with Nikonos and flashbulbs in the 70's catching the expended bulbs and popping them into a mesh bag. It was frustrating beyond belief. the keepers were maybe one every couple 36 exposure rolls. a friend and I cofounded a dive shop in the mid 70's. Digital came like an angel descended upon me. The intervening years were spent in college and veterinary school. vet medicine overwhelmed my world for many years. retired now , building energy efficient structures , a long time passion , and loving the science and art of it in the age of easier to find so much information. my UW cams evolved from the nikonos to the Nikon d200 then d300 and wonderful aquatica housings and trusty Ike 125's and 160's. I've got some juice still in me so I want to throw my d850 in a used aquatica housing and take another run late in life. I thank Alex Mustard and Martin Edge for teaching me what I know. I read Martin's book cover to cover twice before I got into digital and read as many of Alex's articles as I could. So inspiring. this morning I was on this site and saw that Alex was as well. so close to greatness.... ha! Thanks for building a great site and community.
