Phew - Think I have now worked out how to post to get involved!
I'm Simon H, I'm a professional (land) photographer based in the UK's south coast. I'm relatively new to all this underwater shooting but enjoying that it's so specialized. I started with an old Subal and a 15+ year old Canon 5D and have just invested in a much newer Aquatica paired with the Mk4 Canon, it's all pretty different from the Subal, so feel like I'm almost starting again!
I will no doubt be picking peoples brains to progress!
