I am new to underwater cinematography, and have purchased a Sony a7s II and am getting familiar with it before an important trip to Raja Ampat in October. I have many questions, and wonder if there are others in the community that are shooting with this camera that I can learn from, and compare notes with.
1. Picture Profile? Any thoughts on the advisable "picture profile" for shooting? sLog 2, sLog 3, Cine4?
2. Grading and LUTS? If one shoots with a flat picture profile, how does one properly grade or color correct? I have been doing as much internet research as I can, and this remains a bit of a mystery. I want to start collecting great clips in the proper picture profile.
3. White balance issues? On my first trip with this camera, to Cozumel, I believe that I properly manually white balanced the camera, at a fairly deep depth, but nevertheless experienced a strong magenta cast. Is anyone else having white balance issues with this camera? Is the camera known to be poor in that area, or acceptable, or does it have known challenges that require a work around? It would be great to possess the state of the art knowledge in this area so I can improve my results.
I have posted my first "tests" with the camera, and the results are quite primitive, but they can be reviewed in this Vimeo clip. Anyone that wants to see some raw 4K footage of the first tests, to help me diagnose what is happening, can send me their email address and I will give them access to some raw footage.
Many thanks for your help.
