Thought I'd join after the site being mentioned in Alex Mustards book.
Been using GoPro to create some videos so far (https://www.youtube.com/channel/UCdJTf9dZkR4usidB25Qfp1Q) and I'm a hobby photographer on the surface.
Looking to start getting stills underwater - starting off with Nikon D80 with Aquatica housing (still need to sort out strobes, arms etc.), has a 50mm lens which as a test worked out OK, but have ordered a 40mm Macro to be able to get closer to subjects.
If anyone has any tips on this set up, much appreciated.
