Well, the topic is complex and we should reverse engineering those lights to understand exactly the technique used to drive and dim the led. AFAIK the PWM method cited by Chris is not well suited for video or photo professional lights. Despite this, it is perhaps the most widely used method of adjusting the brightness of LEDs even though in public and private lighting, caveats are used and intl. standards are followed. Then there are other methods similar to switching power supplies that work at much higher frequencies. However, I believe that a light designed for video makes use of constant current drivers. If you are passionate about the subject, I will give you some links.

Yes I know but it is almost impossible to be unique on all social networks. we could have used our name followed by UW Photography Forum or something similar but it was too long and we preferred to leave it that way.

Hi Crasoner, Welcome aboard!

Easydive has unveiled the new housing for Gopro and Insta360 Ace pro with built-in mini dome (split shot I don't fear you!!!) 😄 Actually reading the features it is a 160mm dome so not really mini, especially for a GoPro. the FOV remains the same. Here the product page and a YT video of Alessando Beltrame showing the housing and dome in action. (Video is in Italian but YT can translate it for you). https://www.easydive.it/en/underwater-housing/action-cam/housing-for-action-cam/actiondome-case.980.html

Hello everyone, We have just launched the WaterPixels page on Facebook. The page will not have original content but will be a showcase of our most interesting discussions and articles on social networks hoping that it will attract other image makers with their experiences, contributions and questions. Please help us spread it: https://www.facebook.com/people/WaterPixels/61562852399315/

Nice video and nice idea. You described everything so well that it is difficult to ask you any more questions 😁 I was just reflecting on the fact that this type of diving has really opened up a new world of discovery from a scientific point of view.

Could you share the files and details in the DIY forum? Thank you in advance

In the meantime, let us console ourselves with this:

In my home I have the most expensive doorsteps and paperweights...

The price was so good that I had gone on faith. Now, knowing the Nauticam prices for a new housing and knowing that I may not even be able to sell my GH5 Kit... I think I'll stay that way and maybe invest in a new monitor or new lights. We'll see.

Three weeks ago I lost an incredible deal on a like new GH6 housing. The time I got a confirmation from Nauticam that iy would fit in the gh6 housing and it was gone...

it's wrong to think badly of someone, but you're very often right 😉

Superficial and distorted article to say the least. If this is journalism, I am John Wayne 😄

I read a lot of Canon users wondering if it's a DGO sensor. Let's see when it will be available.

After the last Panasonic presentation in which they used stock photos, the Gerald Undone drama (which later backfired) the R5 overheating scandal, when it comes to new cameras I don't even believe my mom anymore. 😆 To get some reliable feedback, I will wait for the camera to get into the hands of ordinary people. All influencers are unreliable if not corrupt. Canon's presentation and the various media outlets were so vague and contradictory that DPreview had to put a patch on it with this clarification. https://m.dpreview.com/articles/3364448295/canon-eos-r5-ii-for-photographers-what-you-need-to-know?slide=2 We await the clarification on the video section.

Maybe @Aquatica could help us?

Done already 😉

Based on the lens + diopter you have a small focus range. For Nauticam there's a chart with the most common combinations.

Hi Roman I am sorry that you had this experience with camera & scooter but its use it's completely different from what you describe. What you wrote happens for the reasons I wrote above. I assume that before carrying a camera on it, one is completely confident using the scooter. Although at first glance it may seem simple, its safe use is not trivial even in recreational diving. There are even courses to learn how to use it safely. In addition, there are different types of scooters, and as for camera mounts, there ar different models with different characteristics. No Gopros there. On the first photo I'm using a GH4 in Nauticam Housing, 6" dome and Keldan Luna 8 lights. On the second photo, a beloved Nauticam GH2 with two custom lights bigger than HF-1 strobes. Now I have a monitor too. Me and my friends use the camera (GH5, A7SIII, A6700, A7RIV) with scooter, lights and strobes nearly in all our dives. In the early 2000 we were using huge Amphibico Housings for shoulder mounter Sony camera on Gavin scooters. I drive the scooter with one finger and he goes just straight. When I leave the hand, it stays just in front of me. From the trash bin (wrong settings) last Sunday, my buddy filming @80m/262ft. For a limitless experience just use a detachable camera mount. The Suex camera mount permit to remove and reattach the camera underwater with a single lever push pull. This short documentary was 100% shot on scooter mounted cameras. We had no creative constraints in making it.

Plenty of posts about red filters 😜

Gentlemen, I moved all the last few posts since were no longer talking about the battery pack but about the grand schemes of life. You can continue the discussion there and leave this thread only for posts related to the battery pack. I trust in everyone's ability to respect the rules of peaceful digital community life https://waterpixels.net/forums/topic/1482-retra-strobes-pros-cons

Do you have an example of bw critters and size you got with these lens? Thank you in advance
