RETRA Lithium-Ion Battery Pack
Davide DB replied to Jay-11's topic in Lights, Strobes, and Lighting Technique
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 -

Canon EOS R1 flagship sports - photojournalism camera Announced
Davide DB posted an article in Product Announcement
Canon has officially announced the EOS R1, a 24MP Stacked CMOS sensor mirrorless camera designed for professional sports and photojournalism. Key Specifications: 24.2MP stacked CMOS sensor 100% AF coverage with cross-type sensors Up to 40fps blackout-free shooting (JPEG+Raw) Pre-capture for photo and video (1/2 sec. for photos, 3 or 5 sec. for video) Eye-controlled AF with enhanced eye detection Activity AF mode trained for specific sports Pre-registered person AF priority Blur/out-of-focus image detection In-camera processing with neural network noise reduction In-camera processing with AI upscaling 6K/60p internal Raw video capture DCI-4K capture up to 120fps Canon S-Log2 gamma profile The EOS R1 features a 24MP Stacked CMOS sensor that reads out nearly twice as fast as the existing R3. It can shoot stills at up to 40fps and capture 6K/60 Raw video internally. The Dual Pixel sensor has its sub-pixels rotated in alternate lines, providing cross-type autofocus across the entire sensor region. The "Digic Accelerator" co-processor allows it to handle complex algorithms developed through machine learning for various AI functions. Additionally, the EOS R1 boasts the largest, highest resolution, and brightest electronic viewfinder ever offered in an EOS camera, featuring 9.44 million dots and 0.9x magnification. -
Canon's EOS R5 Mark II is the company's latest high-end, full-frame mirrorless camera, now featuring a Stacked CMOS sensor and many autofocus capabilities from the flagship R1 model. Key Specifications: 45MP Stacked CMOS sensor Eye-controlled AF subject selection Up to 30fps continuous shooting with blackout-free viewfinder In-body stabilization rated up to 8.5EV correction, coordinated with lens stabilization Pre-burst capture (JPEG) 8K Raw video capture up to 60p Canon C-Log2 profile Waveforms and false color display AF trained by machine learning for specific sports AI-enhanced post-shot noise reduction or upscaling 1x CFexpress Type B, 1x UHS-II SD card slots The Canon EOS R5 Mark II will be available starting August at a recommended price of $4299, which is a $400 increase over the original model (though less expensive in real terms when considering inflation).

It depends on what drink they used on the alcohol induced young female target group. Pure malt whisky is OK.

Blackwater Photo Shooting Techniques?
Davide DB replied to Davide DB's topic in Photography Gear and Technique
Thank you Giancarlo, very informative. -
I see that there is a fair amount of interest in blackwater diving and thought it would be appropriate to open a thread dedicated exclusively to this specialty from a photographic point of view. What are the best lenses according to the size of the subjects? How best to use strobes? Besides strobes, what are the best support lights to help focus the camera and look for subjects wandering in the black water? Advice on logistics and the best locations/periods for this type of diving (this is a common topic with video makers). Some time ago our member @Giancarlo M. posted a nice article on using the Nauticam EMWL lens (the desire of many) in this particular context. I repost it here for reference.

My friend's solution was more basic and cheap. His Subtronic strobes are an old model with integrated battery pack. The guy just moved the front slave sensor to the back behind the rear plate and glued a small plastic tube for fiber connector. But the most economical solution was to place adhesive fibre adapters on the front slave sensor. I repeat, I know nothing about underwater photography and flashes but he says it works perfectly 😇

Yes, I remember that thread on WP...

Very interesting ideas. You photographers are lucky that by adjusting the shutter speed you can vary the background. Unfortunately on video it is not so easy and in a few metres of water, even with a snoot, you have little margin to intervene. Maybe I should bring along a black background and set up a small stage. 🤡

I don't want to talk nonsense because I don't understand anything about underwater photography. He has two Subtronic flashes. A couple of them he had modified by the guy I was telling you about and a couple he used these adapters sold directly by Subtronic. In the end he's happy with them and says they're not worth modifying. Manual contro only of course. https://www.subtronic.de/produkte/Optocontrol-Sklavenblitzausloeser.66325.php

Black-water video shooting techniques?
Davide DB replied to bghazzal's topic in Video Gear and Technique
Here we are speaking of video od course but what's the best Canon lens for AF in this kind of dives? Seeing the Aquatilis project her in the Med, most of the critters are huge. Something I would shot with the 12-35mm (24-70 FF).- 72 replies

Here in Italy they are well known and were considered expensive. There is a technician here in Italy who can change batteries and service them at very low prices. He recently modified a couple for a friend of mine, making them fibre-optic compatible.

I missed this thread too... I have been using a scooter for about 20 years and have been shooting with a scooter for about 15 although for the last two three years I no longer mount the camera on the scooter because I find it too limiting (broader discussion). I have an old Suex 14 and have mounted several M43 cameras with 6" domes or the WWL. I have two Keldan Luna with floating arms, monitor and have no particular problems. The scooter is fine as long as some precautions are observed. The scooter and the photo/video kit must be individually neutral. That way you get a balanced set. So if you want to detach the camera from the scooter to photograph by hand (and the camera attachment allows this easily) you can do it safely. It is also a matter of safety. You may have to separate them and the two objects remain neutral and fully operational. Some friends during long cruises position the camera and headlights perpedicularly to the longitudinal axis of the scooter (direction of travel) to have less friction but I have never had a problem with this.

Same advice here. Lately I bought on Ali a couple of no brand clamps and for the first time they are not too bad. I have some Nauticam clamps and during the years I collected clamps of different brands and I mix them without paying attention. When I move and adjust the arms underwater I can tell which Nauticams are without looking, only by how smoothly and precisely they adjust.

UW Imaging Evolution Thoughts.......
Davide DB replied to dhaas's topic in Photography Gear and Technique
Sony hear you! The new ZV-E10 Mk2 vlogging camera has a dedicated bokeh switch which creates a defocused background. -
Hi Jake, A warm welcome to the forum! I'm sure you'll find other old wetpixelers like you.
