Ive dig a little more into MotionCam discord and its seems the App is going in right direction with RAW output very fragmented android market doesn't help. Not all lens available in the smartphone work with the app Not all available resolutions are available in the app, especially 4K60 Not all Android versions give the same access to the app Not all smartphone manufacturers give API access to the app Some smartphone need to have customised android version RAW output is very task intensive. The developers seem to be very knowledgeable in what they doing but im same cases their hands are tied due the reasons above. So ive turn my attention to the Iphone 16 Pro and 16 Pro max The Blackmagic camera seems to be the best app for filming and now it's possible to choose different type of bitrate. For HEVC (H.265) the max bitrate is 81Mps in 4K60 For Apple ProRes 422HQ 4K60 the minimal write speed is 220Mbps For Apple ProRes 422 HQ 4K120 the minimal write speed is 440Mbps Apple ProRes 422 HQ: A higher-data-rate version of Apple ProRes 422 that preserves visual quality at the same high level as Apple ProRes 4444, but for 4:2:2 image sources. With widespread adoption across the video post‑production industry, Apple ProRes 422 HQ offers visually lossless preservation of the highest-quality professional HD video that a single link HD-SDI signal can carry. This codec supports full-width, 4:2:2 video sources at 10-bit pixel depths, while remaining visually lossless through many generations of decoding and re-encoding. The target data rate of Apple ProRes 422 HQ is approximately 220 Mbps at 1920 x 1080 and 29.97 fps. With the new Iphone 15 pro e 16 pro & Max its possible to film 4K60 using HEVC format, for ProRes 422 HQ format 4K60 is possible only with blackmagic camera app, the stock camera app dont work Only the Iphone 16 pro & Max support 4K120 ProRes 422 HQ and is required a specific SSD attached. Scrolling through Reedit it seem lot of filmmakers are using Smartphones with External SSD attached.. For us Underwater divers, at the moment, i think theres a solution that requires the following for 4K120 in ProRes 422 HQ Iphone 16 pro (256gb, 512gb, 1TB) Divevolk Max Plus Lexar Go Portable SSD 1TB or 2TB Print customs case The iPhone 15 pro size is 14.6cm The iPhone 16 pro size is 14.9cm The lexar GO is 2.5cm total size iPhone + lexar is 17.5cm The divevolk cases are 18cm

@Maria Munn There´s any underwater case for the iPhone ( with touchscreen support ) that let us fit some SSD for external storage.. ?? Because to get 4K60 with ProRes 422 HQ its required external SSD ProRes 422 HQ models 256 GB, 512 GB and 1 TB iphone 15pro 4K60 (only with external ssd minimal 220MB ) iphone 15pro Max 4K60 (only with external ssd Minimal 220MB ) iphone 16pro 4K120 (only with external ssd Minimal 440MB ) iphone 16pro Max 4K120 (only with external ssd Minimal 440MB ) this article cover all the supported models https://www.idownloadblog.com/2023/09/28/how-to-record-prores-video-iphone/

Small Spider Crab not very happy with divers 😂 For some reason the FW Labs assumed the DIVE=1 has permanent so my last videos have excess of reds, try to fix it with davinci resolve. But im not very happy with sand color. Visibility was not the best.

I want to share this info about Motioncam pro Motioncampro for android is a unique app that work on android smartphones that capture the RAW FEED from camera sensor and everything is converted "on the fly" to log process into video. Motioncam > image signal processor > Raw image file > encoding While other stock apps Stock app > Image signal processor > post processed > encoding This means that whats inside the Raw file is whats the sensor sees. Ive being watching few youtube videos that are very impressive, like this for example Mirrorless 5000€ camera VS 1200€ smartphone Canon R5 MARK ll VS Xiaomi ultra 14 8K RAW 12 BIT 8K RAW 10 BIT Motioncam Or Iphone 15 PRO VS old Android Smartphones with motioncam Motioncam pro FAQ What means "RAW_SENSOR" in advanced settings? "RAW_SENSOR" is a 16bit container with 10bit worth of data! Most sensors capture data in 10bit! MotionCam cam write on external ssd? Yes it can is important to have an USB 3.0 connection For what is used "Split Raw" from settings? The biggest challenge in order to capture raw data, is to have the the speed to write it so on older devices you can try to imbue the speed by allowing a secondary write thread (for example you can write in dual mode 1. internal 2 external SD card, or 1 internal 2 external drive), this should improve overall capture time Why i cannot see all the lenses in MotionCam? Unfortunately on some devices access to Raw Camera Api is limited by the manufacturer eg: Samsung Tele lens Also sometimes is limited trough android version eg: Oneplus 8 Pro Android 11 has access to all lenses, while in Android 12 only main camera How to capture RAW data on SSD or any custom folder? MotionCam captures by default on a private internal folder were data cannot be accessed by "File Explorer". If you want to capture on SSD (or any custom folder) select PHOTO mode then click on Options Wheel , there click on " Select Video Storage Folder" button

Anyone using Android the best app at the moment it seems to be the motion cam pro (29€) with ability to export RAW on Android smartphone, theres a support discord group for more information https://www.motioncamapp.com Regarding the IOS the most popular for video its seems to be the blackmagic camera app specifically optimised for the iPhone and with inclusion of LUT. https://www.blackmagicdesign.com/products/blackmagiccamera For photography Photon or Halide for IOS seems to be good options https://halide.cam https://photon.cam

@Maria Munn These divers are from my dive center, some of their pictures is with smartphones iphone 15 https://www.instagram.com/filomenasapinto_oficial/ xiomi (dont know the model) https://www.instagram.com/rui_palma_photography/ samsung s24 ultra https://www.instagram.com/pedroavasco/

The last couple years the smartphone market has exploded and manufacturers compete between them to implement the best cameras/sensor in portable devices. With the recent implementation of easy to use underwater cases it's a new era for underwater photography and filming. Lets try to understand whats the best feature a smartphone camera can have for underwater use, together with the best app for video & Photography. In Random order in terms of importance for underwater we should look for: Stabilisation Image quality (Noise, Texture, exposure, color, artifacts) Field of View Slow Motion RAW files output Zoom AI integration Auto Focus Bonus Feature (underwater mode)

And there tons of other options

The verge review iPhone 16 pro mention about tonne mapping The iPhone 16 Pro allow you to exclude yourself from this narrative entirely with a huge upgrade to the Photographic Styles feature that allows you to adjust how the camera processes colors, skin tones, and shadows, even after you’ve shot a photo. You can pick between five “undertone” settings that are meant to adjust skin tones and nine “mood” settings that feel a lot like high-quality Instagram filters. You can shoot with a live preview of any of the styles, and then you can tweak the settings or even switch styles entirely later on. And all of these styles offer three new fine controls: there’s “color,” which is basically saturation, and “palette,” which is the range of colors being applied. Most importantly, there’s a new control called “tone,” which lets you add shadows back to your photos. It turns out Apple is using “tone” in this context to mean “tone mapping,” and in my tests, the tone control allowed me to reliably bring the iPhone’s image processing back to reality by turning it down. The tone control is semantically aware — it will adjust things like faces and the sky differently, so it’s still doing some intense computational photography, but the goal is for you to be able to take photos that look a lot more like what a traditional camera would produce if you bring the slider all the way down. (You can also go all the way up for the most intense smartphone HDR photos you’ve ever seen, if that’s the sort of thing that makes you happy.) Turning down the tone control felt like a sigh of relief — I prefer photos with less aggressive tone mapping way more than the default iPhone 16 Pro settings and the photos produced by the iPhone 15 Pro. It’s like a haze is being lifted; images are a little punchier, a little more present. You might feel differently, but I like shadows and highlights, and the addition of the tone control lets me have them on a phone camera without jumping through the hoops of shooting in RAW and processing the photos myself.

which camera did you use, the sony or the TG

A little bit of history about GPLOG and LOG-BASE 400 Copy & Paste from gopro labs by David Newman NR01=1 is pretty close to turning all the noise reduction off. However it doesn't disable Bayer processing for things like dead or stuck pixels, and lens shading, all the processing that normalizes the image. Setting NR01=1 and not increase BITR could be an issue for some scenes, as compression will eat noise/detail in maybe a less pleasing way. Yet NR01=1 and BITR=170 (or higher) will have you covered for the more demanding scenes. NR01=50 is simply a 50% blend on the noise reduction path with the source image. NR01=10 is a 10% blend (10% reduced, 90% Source.) NR01=1 is not 1% blend, as at that point it stops blending. The denoise is the stage before compression, so with sufficient bit-rate you can do more denoise after compression (if at all, I often like the natural look.) 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. https://github.com/gopro/labs/discussions/1217

Last dive of 2024 Gopro 13 FW labs 4K60 8:7 crop to 16:9, no color grading

Ive check their forum lately and the DJI Osmo Action 5 pro, it seems it have a lot to be fix in the future. Weird color mapping wrong white balance exposure issue HDR issues Their forum has being very active with people demanding FW updates for does issues.
