@Gmsalterego give a try to gopro labs firmware You can create permanent presets for gopro 12 and you can change them underwater according to your needs important: QRcode start by $ will be disable after reboot except if you use $PRES + preset name QRcode start by * will be permanent too all presets even after reboot example *BITR=170 this will be available in all presets even if you reboot (higher bitrate ) Preset WBKL (white balance lock) it will lock the WB 1 second after the recording started

A buddy of mine uses white mask and fins, so i know its a good starting point to achieve good reference before cutting any footage. Rocks, sand, torch light, anything white or close to white it also can be used. this video is also a good starting point to learn davinci resolve.

Im not expert But to white balance the footage, the "eyedropper" is one of the recommend tools It’s for getting your footage to a neutral color grade starting point using white as the reference.

By using step 2, adjusting RGB to the highest Value, the software automatically adjusts temperature and tint (step 3)

Found the Video that help me a lot when i started

Some Tips When your render keep instagram video below 1gb and use quality 200.000kb/s to maintain the quality I film in 8:7 on gopro this allows to crop video 16:9 or 9:16 without quality loss

@Kristin YouTube videos for davinci underwater there are severals videos, it doesn't exist one video show it all, its impossible. Start with basics tutorials from here https://www.blackmagicdesign.com/products/davinciresolve/training and here " davinci tutorial for beginners on youtube" later go here : underwaterphotobali https://www.youtube.com/@UnderwaterPhotoBali learncolor grading https://www.youtube.com/@LearnColorGrading Then go to more complex stuff from here: daniel batal not underwater related https://www.youtube.com/@Daniel_Batal cullen kelly https://www.youtube.com/c/CullenKelly/videos To start : Go to projects settings and create a few "presets" and choose respective color space, resolutions, output, HDR, SDR (i use davinci YGRB color management , SDR to SDR 2020 ) etc etc example: 1- default 2- instagram 9:16 3- youtube 16:9 With this save "presets" it will save you tons of time to start new color editing according to the project You will "load preset youtube 16:9 " with the settings you select before You will load preset instagram 9:16 with the settings you select before Add movie to Master, create timeline, and you will notice the tick box "use project settings" that are 1,2 or 3 that you select previously. Open timeline 1- first click pencil 2- go on top of movie and try to find white area get the highest value possible R-255 G-255 B-255 3- this will adjust color temperature and tint. 4- use contrast between 1.100 and 1.200 without clipping the scopes between 0 - 1023 5- keep the lines above 0 and below 1023 to avoid clipping 6/7/8 - adjust them without clipping The program is a bit complex for new starters, my advice is "be persistent" because when you learn the basic, is getting easy on each use. Theres hundreds of settings and specs. Search for terms on youtube to "change background underwater color from green to blue" for example. YouTube is full of good tips-

@Davide DB heres link of 4 raw videos made today with gopro 13 2x standart videos 2x log videos No filters, no AOI external wide lens, just 2 x dive lights 2500 lumens each I can't get accurate colors with LOG compared with what im getting with standart/Natural , maybe you can try to calibrate the LOG videos and share the results back. Looking forward to see the end result from GP-LOG https://www.dropbox.com/scl/fo/4vvbaqd9ob7o59943mx9h/AIeRNqsh42ruXzktJhjkHgc?rlkey=pk1zpi0xxwc2dpu7xxq9yqpud&st=th25ealw&dl=0 color GP-LOG 8:7 4K60 wide WB auto iso 100-400 ev comp 0.0 Color Natural 8:7 4K60 wide WB auto ISO 100-800 ev comp -0.5 CIAO

Also DavidNewman already explain the Flat or Gplog use. GPLog and Log-base 400 For GoPro users they are not exposing for a classic grey point. The exposure logic in the camera is the same for all color profiles, where ISO 100 is the best dynamic range. My guess, the system exposure is basically a expose to the right system, the brightest reflected objects (white clouds) are set to be near the clipping point, so your dynamic range is in the shadows. The linear light data is then encoded with a curve. For Natural and Vibrant color profiles, that would be a gamma curve, plus global and local tone-mapping, and a lot of GoPro magic look stuff (I don't know the math for.) For Flat color, the GTM and LTM are off, and the curve is Log-base 113. This was development for HERO3 as a optimized encoding curve to preserve the most dynamic range for those sensors. The curve was designed for film and television production for which GoPro was being used extensively for crash cams. Flat using Rec709 color primaries, unless you are using Labs with WIDE=1 (note: the very first HERO2 Protune Flat 24p, use native color for the film projects of the day.) Flat also as a lifted grey point, but again for GoPro, middle grey is not technically important for encoding the best dynamic range. But Flat with a EV at -1 or (-0.5) often produces a nice result with limited or no color correction. GPLog is log-base 400, but otherwise pretty much the same as Flat, no GTM/LTM, but with a wide gamut as the default. The enhanced shadows can maybe get you half a stop more dynamic a range than Flat with today sensors. GPLog was partly to address a user misunderstanding that they already had a Log profile. Back in 2012 when Flat was designed, no consumer camera had a named "Log" profile, and users likely didn't want math terms (I guess.) GoPro was either the first (or very near) consumer camera to have a standard log profile (just called Flat.) Move ahead 10-years, nearly all cameras have a "X-log" naming scheme, so GoPro added a new one, GPLog. You technically don't need as much flatness to the look at log-base 400, but that is now a user expectation. Also other camera systems typically have a lifted black level, adding to the flatten look, but I do not know why these codewords are wasted. All 0-1023 codes are used for image signal in GoPro camera, many others only use 128-960/1023 in their log profiles (maybe a Cineon inspired throwback.) Flat at 113 is perfect for 8-bit, GPLog 400 is optimized for 10-bit, both are full range encoding. GPLog has room to grow. source: https://github.com/gopro/labs/discussions/1217

Nice Tutorial But Gopro Flat color profile doesn’t have any LTM (Local Tone Mapping) or GTM (Global Tone Mapping) applied. In My opinion Flat profile is much more challenging to color Grade. A note about Flat Color vs Natural ColorLTM/GTM not Present in Flat Color Flat color profile doesn’t have any of GoPro’s LTM or GTM applied. LTM being Local Tone Mapping, which is a process that enhances the contrast between objects across the whole image (think clarity filter in Lightroom). GTM is Global Tone Mapping, which is a means of boosting shadows and bringing down highlights. The picture in Natural Color has been redesigned from the ground up and actually starts with a very underexposed image so that it can do a very good job retaining highlights once GTM is applied under the hood. If you compare Natural against Flat, you likely won’t be able to get the same amount of highlight saving even after rigorous color correction. This brings me to my second note: Dynamic Range With Flat Color Profile After extensive testing, I haven’t been able to reproduce quite the same amount of dynamic range when shooting Flat Color as I’m able to get with Natural Color. This is due to the GTM process in the image pipeline that happens under the hood as a sort of faux HDR process. This isn’t to say you can’t shoot in Flat Profile, but a watch-out if you want to get the most range out of the box. It’s also a testament to the advanced algorithms found in HERO11. Custom Log Curves with Labs For those interested in digging a little deeper, HERO11 and Mini offer the ability to load custom log curves when shooting Flat Color using GoPro Labs. Flat Color is in-fact a type of log curve, but if you wish to match log curves from other camera sources, you can load those onto the camera. Something to note is that loading a flatter log profile won’t get you more dynamic range out of the camera, it will just change around how the shadows and highlights are displayed. Good news is that 10-Bit color helps quite a bit when shooting in Flat color since the gradations in colors are so similar. source: https://abekislevitz.com/hero11-video-settings-guide/

Gopro 14 is around the corner september 2025 Regarding gopro 13 vs Insta360 see for yourself the raw footage between the 3 actions cameras. https://www.dropbox.com/scl/fo/h46fiofwksw4f9hah6vvo/AKLrcTauOiYg5bHwZb0tibQ?rlkey=isblpfn5bosd7vhbiexugfgpq&e=1&st=2gr6iu23&dl=0 source: Chris Rogers https://www.youtube.com/watch?v=F1OwhtjaPVI Ps: dont forget GoPro has the GoPro labs firmware to squeeze all the juice from the action camera for underwater. https://gopro.github.io/labs/

Got a reply Its paid on boardon arrival..in cash…860$…5 days park fee..

Matthias Lebo shared a video with divevolk + AOI UWL-O3 lens Its required M52mm adapter for the wet lens + M67 to M52 adapter to attached it. The results on iPhone 16 pro max looks very encouraging, no distortion and no blurriness

thanks what about park fees, ive read some liveaboard companies are supporting park fees (172$ day) for 2025, but no word for 2026/27 Are the park fees paid in Mexico when we join ?

Its ok to take gopro13 (400€) + wet lens (200€) + 2 dive lights (600€) and get taxed 16% ?? its almost 200€ in tax

Iphone 15 pro max backmagic camera VS Samsung s24 ultra with Motioncam

Take a look on discord group about your samsung s24 whats is currently supported. https://discord.gg/2XeqnBWF this is their youtube channel, they are very active. https://www.youtube.com/@MotionCam

Actually ive being following the Motioncam discord group, ive made some request to developers like add Presets The "big feature of motioncam" is to record to Raw bypassing all the manufacturer implementation. At the moment i would approach with caution while using MotionCam for underwater, unless your android smartphone support all cameras sizes without frames drop or overheating out of the box, because due the fragmentation of android hardware some smartphone need to unlock the bootloader. The interface of motioncam is also not friendly at all for underwater. Since im more iPhone user, my latest experimental was with UWACAM, really nice app specifically made for underwater use, supporting in video Prores422 HQ up to 240FPS, color space P3-D65, apple log, rec2020 and LUTs In pictures it support Apple ProRAW up to 16BIT

Beta program for the Osmo action 5

@TropicLeslie I have a question I see you have a video coming about alternative lens for the divevolk, im looking for a glass (was recommended) wet lens for iPhone 16pro/divevolk, and i really want to avoid the corner distortion. Do you think the stock divevolk lens is good enough, or it's better to get some m67 glass lens ?

Who ever uses stock firmware in the Gopro 13 black, theres a new firmware V.200 with underwater improvement of white balance capture..

@CaolIla Thanks, really interesting My travel agent works with emperor and i was looking for the offers I wonder if 14 days worth it, or 7 days is enough I have an eye of the Southern Shark Adventure and im also looking for the full moon and new moon to avoid high/low tides and stong currents The 14 days seems tempting.

Whats the Best time of the year for Maldives Liveaboard ? North or South ? Big pelagic, Whale shark, manta rays etc.

Today one of the divers in my group had the new Weefine WFH07 smart housing with iPhone 16 Pro. Looks nice and well built, it uses dedicated DiveIT App. It support RAW picture, 4K120fps video, HDR and ProRes It also has built-in electric drive air pump. But in my opinion the big selling point is the possibility to use strobes and connect optical cable to the weefine housing that match the iPhone Photo DiveIT app.
