Thanks for the great feedback. I am new to shooting underwater and hope to learn as much as I can before my next film oriented dive. I have a 5D mark3 that I am considering buying a housing to shoot with. This shoot was very spur of the moment, I was filming top side for a cruise line and was dropped off from my job in St. Lucia. One of the guys on my team had a brand new GoPro Hero 3 and we were going wreck diving, so I just said, "why not" and my wife and I shot it.
In cutting this I really did want to give the viewer the feeling of diving, this feeling is what hooked me, and I hope to share this with people who have never been deep underwater.
I'm really hoping it's not too terribly long, I will consider chopping it down if I hear that more.
The GoPro definitely suffers from limited DR, I'm hoping the 5D3 will be enough improvement. I am a bit worried it will leave me wishing for more, such as a 1DC or RED or Blackmagic. Something with RAW or at least LOG.
The GoPro 3 has a flat port, so I don't think it's the housing, I think it is the optics therein. I can be wrong here, I'd love to hear some more opinions on it.
Thanks again for your comments!
