I found the time to do a little write up on underwater white balance that includes some of the techniques I use Hopefully this is useful to most people out there. I have focussed on GH5 picture profile but I guess other camera won't be much different https://interceptor121.com/2019/09/24/the-importance-of-underwater-white-balance-with-the-panasonic-gh5/
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. George L. Paul
Despite almost zero information within the Red colour channel, the R3D files from the Scarlet W still grade up nicely. Took about 12 nodes to get to this point but considering the starting point of this clip, it turned out reasonably well, especially given the conditions. Conditions were tough with maybe 5 metres vis, surgy and lots of floating particles. This shot was about 18 metres deep. Scarlet W, 5k 50fps, Nikon 16-35mm and 8 inch dome on the Gates Pro Action Housing. Graded in Davinci Resolve 14.
I'm interested in views on colour correction / grading software. I've been doing my colour correction in Sony Vegas Pro, mostly using Color Curves, but I'm getting sick of dragging those fiddly little tangents around, and I hate the fact that there's no undo functionality. I'm upgrading to a new computer in the new year and it's time for a better tool. I'm a PC person, so it has to work in Windows. I'm a Vegas Pro user, but I'm probably going to invest in the full Adobe CS suite in the new year as well. Still likely to use Vegas as my main NLE though. I need it to work with my old HDV footage and newer AVCHD / DSLR footage. Here's what's in my mind: DaVinci Resolve Lite - free Adobe Speedgrade - $969 standalone but included in the CS6 Master Collection or Production Premium suite Magic Bullet Colorista II - $299 (might need other Magic Bullet products too?) Technicolor Cinestyle Color Assist - $99 - New kid on the block Any experiences? Views? How do they compare in terms of ease of use, features and performance? Also, since none of them appear to plug into Vegas, do they allow rough cutting of footage along with color-correction, with a view to exporting and EDL etc. to Vegas after colour correction?
