(The one in the UK) I certified in 2003, and started taking photos (with an Oly C5050Z) soon after. Switched to an E-520 some time later. I took a break (to do a Photography B.A.), but kept pool shoots up, with Canon 5Ds (https://drewk.photo/showcase/underwater/ - note this is NSFW). I’m (warm water) diving again now, and have just bought an Insta360 action cam, looking to get some moving image work done.
