Huge thanks to the entire team at The Underwater Tribe for taking me diving

Gates Pro Action Housing and Gates GT-14 Video Lights were used.
The Nikon 70-180mm macro lens was also used and turned out to be a very versatile lens.
The R3D's were edited and graded in Resolve 14.1 and a couple of clips were post stabilised.
There wasn't a great deal of grading needed as the H20 OLPF works nicely, especially when white balanced off a white slate.
