The best way to get some concentrated coaching in underwater photography is to join a dedicated underwater photography diving trip where you can take lots of photographs and improve technique on wrecks, walls, caves, marine life and anything else you want to take pictures of.
The overall objective is to provide a trip optimised for underwater photography, where both seasoned photographers and newcomers can mix with like-minded divers and, more importantly, enjoy excellent diving and take home some fantastic pictures.
As with the PADI Underwater Photographer specialty course, I am too busy with photographic work to actually manage and organise a schedule of such trips. If you are a tour operator or run a dive centre or boat and would like to discuss running a photography week, please contact me to discuss possibilities.
