Thanks, wasn't sure it would be worth while in 8bit - I'll have to give them a try.

I'll have to give white balance with the lights on a try. I'm using a pair of Kraken 15k lights with their cyan filter. I do the same thing - small grey card on a retractor. Looking forward to shooting some video but as a new CCR diver I need to a bit more time in the water before bringing the camera. Today is a dive day, but it's 33°F, winds gusting to 35mph and raining... Trying to convince myself it'll be calm and quiet below 15 feet (Northern Minnesota quarry)😂

Thanks - I'm new enough to video I've been staying with the Std profile. From what I understand the A7c's 8bit color limits its color grading potential anyway.

Thanks for mini master class in UW lighting Jim. Super helpful. One question. When you do a white balance you do so with the cyan filtered video lights on? The Kelvin video suggests doing so when they're off.... but I imagine balancing with the lights on results in a more accurate WB on the lit foreground, at the expense of a somewhat inaccurate WB for the unlit background. Your video is the perfect UW example of what I try to do topside with lighting... make it look like it's not lit. Beautiful footage!

Good advice - I'm an old photographer but a very new to video. Would't it be nice if video WB was as easy to manage as that of a photo RAW file. Not much sand round here and don't think my hand would work either😂

Wow - that's crazy! My Sony's not making color shifting like that, it's just that consecutive custom WB have very different colors. Oddly similar he's arrived at a similar solution... Thanks for sharing - particularly as I've considered upgrading to an A7sIII.

Intersting idea... might have to give that a try - thanks

Might be technique - I've used a white patch on my fin, but generally a card held at arms distance and oriented in the direction of the intended shot. and you're correct - no video lights. I wondered if there is a red channel boost built in to the UW auto WB setting...

Manual WB without the filter gives poor color and inconsistent results. Repeated manual white balances at the same depth, same ambient conditions just minutes apart have very different colors. I've heard it has something to do with the A7c maxing out at 9900K. no question x-rite is correct... my camera often reads the white card as being too bright to complete a manual WB, and with the red filter in place, the white and grey card give similar manual white balance readings. I honestly don't care about super accurate color, I just want consistent color. Maybe I'll bring the white card along next time. Thanks for the input.

Wondering if this might be a work around for my Sony A7c's limited manual WB capabilities... I've been using a Keldan red filter between my WWL-1 and the 28-60 port getting decent results white balancing off a grey card. It works but I really don't like that piece of glass between the port and wet lens. it's a pain to mount, easily lost if I remove the WWL underwater and I worry about scratching things. It's also costs 2 stops of light. I don't exactly understand how UW auto differs from auto white balance, but when I've used UW auto in the past it provides nice color, but it can, and usually does shift mid shot. So I wondered if I could use UW auto WB, hold my grey card in frame long enough for the camera to adjust then activate WB lock (mapped to a rear button) might be a solution. No red filter, accurate color, no loss of light... Lakes still frozen round here so haven't been able to properly try it out. Anyone know anything about underwater auto WB? Anyone use it with WB lock? 🤙 ps. shoot fresh water lakes, generally 2-10 meters, occasionally deeper in Lake Superior.

I have a Cinebag Grouper XL. I love the pockets, padding and its ability to be a rinse tank but their quality and customer service is lacking. I use mine for local shore diving. Fresh water in Northern Minnesota, so it's lives a pretty easy life. About a year ago the top bungee anchors started to unravel. Then a pocket shock cord pulled out. I reached out to Cinebags via email twice - gave them a couple weeks as they had an update in progress banner on the site. No response, so I messaged them via Instagram, twice. No response. They did respond to my third email, sent me a return auth form to fill out, and suggested they'd send me one of their kit bags for my inconvenience. Sent it in for repair but several weeks went by and I didn't hear anything. I emailed three times over the course of month, and my third message got a "I'll check on it" reply. A couple weeks later the bag came back with the top bungee anchors repaired but the pocket shock cord still torn out. And that "kit bag" they offered for my inconvenience... nowhere to be found I like the bag but anticipate some off season sewing to keep it functional. I'll spend my money elsewhere when I need another bag.

I often find that getting good color in Lightroom is tough. Lots of WB adjustments that I'm never thrilled with. In Lightroom using a custom white balance off something neutral in the frame works wonders. I've also painted my fins with a rubberized grey material that I occasionally snap a photo of to later establish a baseline WB in LR. For video I use a dedicated grey card.

Greetings, I've been an occasional diver for ~30years. A wildlife photographer for nearly as long. Diving was infrequent enough that I never invested in anything beyond a GoPro for underwater use, but a few years ago I started diving Lake Superior and the local lakes and quarries regularly. A Sony A7c in a Nauticam housing and a couple Inons and kraken video lights have me really excited about local diving. Looking forward to learning lots, and hopefully, sharing ever better images.
