When choosing a housing and camera there are two annoying things to consider – you might flood or lose it. This is one of the reasons I dont recommend using your phone. Whilst the cameras on phones are getting increasingly sophisticated, the chance of loosing it to a leak or simply dropping it are possible.
I first started underwater photography in 2003 with a Nikinos V film camera. In 2004 I went digital and started using compact cameras in housings. In 2011 having had enough of life sitting behind a desk I became a scuba instructor and housed my DSLR and trained and started working as an underwater videographer, eventually running my own business in Thailand. After smashing my head in on a motorbike without a helmet - please wear a helmet, you never know when a drugged up idiot will come around the corner on the wrong side of the road - I had a brief sojourn into working as an underwater photographer in the Canaries, before returning to the business in Thailand filming and teaching videography. I am currently having a break from the water caring fro my Mum in Northumbria, where I don't get in the water quite as often, but it does give me time to share a bit of what I've learned in over 1,000 dives with cameras in my hands.
