Underwater Photography with a Rebreather
A ballpark estimate is around 10K euro. It depends on the specific unit. latest, more advanced rebreather are in the 12K euros. Some simpler units can be bought for less than 10K. On top of this you have to add specific training. Each step costs about 1K.

Guys, after countless tests, comparisons and heated discussions, you can't tell me it was all a bad dream 🤣 Edit: I will split these messages in a new discussion.

Los Islotes sea lion rookery...
Beautiful animals. I had no idea wild creatures interacted with divers like that.

Black-water video shooting techniques?
Yes, great footage. It's easy to find incredible photos but few good video. Looking for a Davinci AI plugin to remove swarm and Backscatter from video 😉

Hot Mediterranean Sea
Yes, oceans are huge heat accumulators which they then release in the form of water vapor that then has to be discharged somewhere. Heat = energy. The thing that impressed me the most this year was that apart from the mucilage, when the first autumn swells and currents cleaned everything up, the soft corals seemed to have held up well. at the beginning of October we had taken some beautiful footage of this forest of shallow gorgonians that seemed to be doing just fine and the idea for the video had started from here. Then editing the video we realized that we needed more footage and so, last week, we went back to the exact same spot. My buddy had a wide angle setup and I had the macro because at the base of the gorgonians we had found some beautiful alcyonarians and I wanted to get some fine detail. Unfortunately, half of the gorgonians were stone dead and there was no sign of the alcyonarians. Unbelievable. Guides and biologists confirmed to us that the process that leads them to death is slow and damage becomes visible even two months after the heat wave.

Hot Mediterranean Sea
I have been informed that my recent posts have been perceived as somewhat melancholy, with a particular focus on the challenges of climate changes while diving in the Mediterranean. Personally, I don't like those who scaremonger as opposed to rampant denialism. But I can't pretend otherwise either. Glorifying (with a magnifying glass) only the beauties of the sea while everything is falling apart seems to me like burying my head in the sand. As divers, we have a unique perspective on the impact of climate change in our seas, and it is our responsibility to raise awareness about these issues. Data from the Copernicus Climate Change Service show that Europe had its warmest summer on record. The period from June to August was the warmest ever on a global scale, with temperatures 0.7 degrees Celsius above the 1991-2020 average. The summer period was wetter than average in western and northern Europe, and drier than average in eastern Europe and the Mediterranean. All this results in the Mediterranean Sea warming at a much greater rate than the oceans. And the results are there for all divers to see. English subtitles

[documentary] ASIA - BBC | Beneath The Waves
IMHO the two best stories are the Moorish idols and the Mudskippers. BBC succeeds as usual in creating real stories by artfully editing the images. The stories about the Sea Bunny and the collaboration between snakes and fish for hunting are also very good but the first two mentioned are incredible. I can imagine the enormous amount of footage required to edit these stories. However, credit must be given to the skill of the BBC that manages to make a nudi walk interesting. It is by no means easy. However, I got the impression that some scenes are filmed in the aquarium but I could be plain wrong. Unfortunately, BBC chose to show only the BTS of the whirlpools.

bonfire dives (light-trap dives)
Maybe this is the reason all use the "blackwater" term opposed to the copyrighted "black water"? AFAIK a copyright/patent is a costly process. I don't get how much money you can get from these rights. So it seems BW diving is highly overrated...

[documentary] ASIA - BBC | Beneath The Waves
Wow, I live in the Mediterranean, which is a basin of water by comparison, and currents are rarely a problem. The only place where currents are raging and dangerous is the Strait of Messina where we dive at the strangest times with tide tables. Here the current easily reaches 6 knots, and depending on the geography of the coast and seabed, impressive whirlpools form that are spectacular to watch. The Greek legend of the monsters Scylla and Charybdis originates here

Vimeo, This Is The End
Once upon a time, Vimeo. For reasons officially unknown (I'll come back to this later) Vimeo stopped being, for us Europeans, a community of video storytellers. (As it still likes to call itself). Basically, in certain regions of the world you can no longer use the video search function and at the same time you can no longer browse other users' videos. I can only see and search my own videos and eventually see a video of another user only if I have its link. Even if I know his name I cannot search for him. I can only see his profile if I know his exact url. This post sums up what happened: https://shortverse.beehiiv.com/p/vime-nooo I am so angry. Because I noticed it by accident and I also looked like an idiot because I as well as thousands of other users thought it was a bug. No communication at all. Out of the blue. The entire UE community lost. Because the membership fee is the same for everyone but I have most of the features disabled. Those who read this thread and, for example, have an account in the U.S. or other countries not affected by this ban might think that this does not affect them. But it absolutely does not! I have several friends in the U.S. who use their Vimeo account for showreels, basically a videocentric Linked-in. In their profile they have written "available for hire." Here, you must know that their profile is no longer searchable from banned countries. And we don't even know which ones they are. I can only access a video of theirs via direct link but I can't go to their profile or search them by name via the search function. This is my following people page: I can see their names but I cannot click on their profile icons. Sounds like a joke. What is the point of these lists now? Just imagine my frustration, I've been a member for 13 years and I've developed a whole network of relationships over all these years and now I can't even see the profiles of people I've collaborated with, anymore. Think about it before you renew your subscription!

Sony Rumors: A1 II Camera + 28-70mm F2
Who knows. Current AFs are all AI-based or more appropriately, with machine learning technologies. Perhaps the new camera will have a more powerful AI chip and new data with which it has been trained. I don't know if this is already the case now, but ideally it would be possible to update the data that the algorithm has been trained with through a simple FW update.

Insta360 Ace Pro 2
Insta and DJI have a physical obstacle that is the FOV of more than 150°. DJI has reduced FOV called “standard” but the reduction is minimal. Insta seems to have solved it with this software correction of underwater mode. IMHO the iPhone is terrible. The edges are unacceptable even by my standards which are quite low. I have never seen anyone mount a wet lens. Then even there, the SOOC colors are awful. Again, until we see a test of someone starting with clips in Log or flat and maybe adding a wet lens we will never know which is better. I am afraid we will never see such a test. For HLG/HDR fashion just use our search engine and see the very controversial results on far more expensive FF machines. For now IMHO it is just a useless exercise in style.

Upgrade to Gopro 13 + AOI UWL-O3 video underwater settings
This is exactly what everyone want to avoid with video. The solution is already here since a CMOS sensor was invented, from a Gopro to an Alexa 35, and it's called Manual White Balance. That translated In Gopro terms is Native WB or fixed (Kelvin) WB along with flat colors. Unfortunately for us, there's no free meal.
