    AOI Unveils Aura Light System Underwater Multicolor Light


    AOI is now shipping an innovative new product called the Aura Light System (ALS-01), an advanced LED torch and optical snoot designed to allow underwater photographers to “paint” with light of any desired color. The second addition to AOI’s “Signature Series,” the light was developed in collaboration with award-winning underwater photographer Ace Wu. (The first product in the “Signature Series,” the UH-GPx housing for GoPro, was a collaboration with underwater videographer Kay Burn Lim.)

    The tech at the center of the Aura Light System (ALS-01) is a multicolor LED capable of producing a palette of 16.7 million colors—and here’s the ingenious bit—controllable wirelessly via your smartphone running AOI’s dedicated app. The software allows you to create 10 preset colors, which can then be recalled at the push of a button on the device. The light comes with an optical snoot, flipped into position when needed, which changes the beam angle from 90° to 7°. Power is via a single 18650 Li-ion rechargeable battery, giving the light a 2.5-hour runtime at maximum brightness.

    The Aura Light System is available as a single light (ALS-01) finished in black, with snoot and clamp, priced at $530; and as the “Signature Series” package (ALS-01S), which bundles four lights finished in white, with snoots, clamps, and other accessories. Pricing of the Aura Light System “Signature Series” is not yet available.

    PRESS RELEASE

    Signature Series 2025 Edition: The AOI Aura Light System with Ace Wu

    The Collaboration Continues

    The inaugural Signature Series was officially introduced at the DRT Show Hong Kong 2023 with the intention of capturing the spirit of collaboration and pushing the boundaries of underwater imaging. The first instalment of the Series featured a collaboration between award-winning videographer Kay Burn Lim and AOI. The result was an underwater housing for the GoPro that redefined the possibilities for the device.

    The Signature Series 2025 Edition marks a new collaboration, this time between AOI and award-winning underwater photographer Ace Wu. “Underwater photography is a reflection of art and mirrors my inner state of thought,” says Ace Wu.

    At the heart of artistic expression lies the drive to push limits and break boundaries. In underwater photography, the challenges and constraints are plentiful.

    Ace Wu is among the few accomplished practitioners of ‘painting’ underwater photos. “Colors add emotions, create a feeling, and are more than just elements in my images,” explains Wu. Currently, equipment used to ‘paint’ underwater images relies on colored filters placed in front of lights. However, the range of colors is often limited by the number of filters available, typically just a few. This limitation sparked the idea behind the Signature Series 2025 Edition: How could every imaginable color be made accessible?

    No strangers to daunting challenges, the AOI design team explored a host of ideas, ranging from the unconventional to the traditional. The final product exceeded all expectations, earning its place in the Signature Series lineup.

     

    The Aura Light System: Painting with Every Possible Color

    The Aura Light System is a revolutionary departure from conventional underwater lighting. At its core is a custom-designed mobile app that allows users to select from a palette of 16.7 million colors. The app communicates with an advanced LED torch capable of reproducing the selected color.

    This LED torch is equipped with an optical condenser that enhances the brightness of the colored beam. It can store up to 10 preset colors, while the app supports simultaneous operation with multiple LED torches. The result is an unparalleled ability to ‘paint’ underwater images with virtually unlimited color options. The Aura Light System also includes an optical snoot that is both compact and powerful.

    The Aura Light System is a clear departure from typical thinking employed by many manufacturers, bringing software engineering and user interaction to the forefront of underwater lighting and photography.

     

    The Aura Light System – Signature Series will consists of 4 LED torch complete with color coordinated mounts and optical snoots in white. The entire collection will be housed in a protective carrying case for convenience and security when traveling.

    The Aura Light System can also be purchased individually, the standard version is in black and will include the matching optical snoot and mount.

    The AOI-UW app is available for download at Apple’s App Store. The Android version will be available later.

    Don’t limit your artistic expression to the tools available, be free to ‘paint’ with the colours you feel.

  • New World Record for Scuba Diving All Seven Continents

    New World Record for Scuba Diving All Seven Continents



    Scuba divers are known for being well-trodden world travelers. But one man has taken dive log travel to record levels.

    Diver travel influencer Barrington Scott has recently set the Guinness World Record for fastest person to scuba dive all seven continents in a row—in just 19 days, 19 hours and four minutes.

    The intrepid diver covered more than 27,000 miles to accomplish the task, which took place in late November of last year. New additions to his logbook include stops in Thailand, Malta, Egypt, Malta, and Argentina. The record-setting plunge took place in the frigid waters of Antarctica.

    “When I finished my final dive, I called my sisters first to share the good news,” Scott told Essence.com.  “I could feel the pride and excitement in their voices—it made the achievement feel even more real.”

    Scott’s journey into the record books is a long time in the works. After dropping out of New York City’s foster care system as an adolescent, he joined the Marines and served in Afghanistan. Following his service, Scott earned a culinary degree and spent a year backpacking in Asia.

    Finally, in 2014 he took the giant stride into diving in the Bahamas and never looked back. Scott eventually worked his way up to Master Scuba Diver Trainer (MSDT) and even authored a book on his adventures, Trent’s Adventures: Deep Sea Discovery, hoping to inspire young ocean explorers of all backgrounds.

    “Breaking a Guinness World Record isn’t just about making history; it’s about showing that we belong in these spaces,” Scott shared on Instagram. “Black explorers, Black divers, Black adventurers—we’ve always been here, and we will continue to push boundaries.”

  • Ikelite Announces “Deluxe Version” Fixed Port Housings for Sony a6700 with Power Zoom 16–50mm Lens

    Ikelite Announces “Deluxe Version” Fixed Port Housings for Sony a6700 with Power Zoom 16–50mm Lens


    Ikelite Announces “Deluxe Version” Fixed Port Housings for Sony a6700 with Power Zoom 16–50mm Lens

    Ikelite has released two “deluxe versions” of its housing for the Sony a6700 featuring a fixed flat port with standard 67mm threads. The housings, which specifically accommodate the camera with the Sony E PZ 16–50mm f/3.5–5.6 OSS lens attached, are designed for use with macro and wide-angle wet lenses with 67mm threads—in much the same way as you would shoot with a compact camera underwater. To make it easier to attach heavier wide-angle lenses, Ikelite recommends using a compatible 67mm-to-bayonet adapter.

    The two housing configurations are as follows: The 200FP/T housing bundles the Sony a6700 housing with the Dual Tray with Dual Handles, Trigger Extensions, Vacuum System, a spare O-ring, and TTL circuitry. The built-in TTL electronics mean that you just need to add a single sync cord or a dual sync cord and one or two compatible Ikelite DS strobes, respectively.

    By contrast, the 200FP/F housing bundles the Sony a6700 housing with the Dual Tray with Dual Handles, Trigger Extensions, Vacuum System, a spare O-ring, and a built-in Fiber Optic Transmitter. The transmitter attaches to the camera’s hotshoe and translates its flash signals to LED pulses that can be read by compatible strobes by manufacturers such as Inon, Sea&Sea, Retra, Weefine, Kraken, AOI, and Backscatter. Strobes can only be used in manual mode.

    Available now from retailers such as Backscatter, the 200FP/T housing is priced at $1,690, while the 200FP/F housing costs $1,715.

  • Ikelite Announces Housing for the Nikon Z5 II

    Ikelite Announces Housing for the Nikon Z5 II


    Ikelite has announced its housing for the Nikon Z5 II. The second-generation entry-level full-frame mirrorless camera is a significant step up from its predecessor. The 24MP backside-illuminated sensor is paired with Nikon’s latest EXPEED 7 processing engine, promising excellent low-light performance and doubling the burst shooting speed with the manual shutter—11fps with full AF/AE compared to the 4.5fps of the Z5. In addition, unlike its predecessor, the Z5 II can shoot 4K/30p video with no crop.

    With its housing, Ikelite aims to get the most out of the new camera. As well as the company’s signature ABS-PC body with transparent back, Dry Lock (DL) port system, and oversized control levers for shutter release and autofocus, the housing can accommodate Ikelite’s USB Charging and Data Transfer Bulkhead, meaning you never have to take the camera out of the housing. Needless to say, if you want to be able to switch between TTL and manual strobe exposure on the fly, you have the option of adding the DL1 DS Link TTL Converter—and a couple of DS strobes.

    Available from retailers such as Backscatter, Ikelite’s Nikon Z5 II housing is priced at $1,895.

    Pre-Dive Checks

    There is no greater assurance than being able to see your camera and o-ring seal through the back of the housing. Our signature open-groove design suspends the rear o-ring in a natural position that is easier to maintain and more reliable than forcing the o-ring into a channel. Once the housing is closed you can see the o-ring form a solid, waterproof seal.

    We recommend using a pump with gauge to pull a vacuum on the housing and check for leaks prior to entering the water.

    Construction

    Our specially formulated ABS-PC blend housing is highly durable yet significantly lighter than aluminum. The light color keeps your camera cooler when shooting in warm, sunny environments.

    Lens Support

    Ikelite lens ports are the lightest on the market, yet robust and capable of standing up to rough surf.

    We support a wide variety of lenses. Most popular zoom lenses and select focus rings can be engaged using simple gearing that puts adjustment right at your fingertips. Zoom and focus gears differ depending on which lens you are using.

    Lens ports and zoom gears sold separately. Refer to the appropriate port chart for compatibility information.

    Wi-Fi Transfer

    Use the camera’s built-in Wi-Fi feature to download photos to another device without removing the camera from the housing. The Wi-Fi feature is only usable above water within close proximity to the connected device.

    Compatibility

    Unless otherwise noted, this housing does not accommodate the use of add-on grips, battery grips, eyepieces, LCD covers, or other accessories.

    Differences in lens and control placement prevent other camera models from being used in or adapted to this housing. We are not aware of any other models which may be used in or adapted to this housing.

  • SUBNOX SUB10KEF 10,000-Lumen Pro Video Light Launched

    SUBNOX SUB10KEF 10,000-Lumen Pro Video Light Launched


    Unveiled at DEMA Show 2024, the SUBNOX brand was founded by professional underwater cameraman Kay Burn Lim, with the aim of creating advanced underwater lighting products designed to meet the needs of working videographers. Now, the new company has put the finishing touches to its first offering—the SUB10KEF, a 10,000-lumen wide-angle video light with some innovative features.  

    The powerful but compact video light is equipped with a specially designed light head and COB LED that produces three different light outputs. One mode is “traditional” light with a CRI of 93 and a color temperature of 5600K, equivalent to daylight. In the other two “Ambient Blue” modes, the light output is equivalent to ambient light at 6–13 meters (20–43 feet) and ambient light at 13–20 meters (43–66 feet).

    As depth increases and water absorbs colors from the light spectrum, white balance controls or red filters are used to restore natural colors, but this causes subjects illuminated by regular (daylight) video lights to appear overly red. Blue filters on video lights results in more natural-looking footage by helping to balance the foreground subject illuminated by the lights and the bluish background. However, the downside is that such filters reduce light intensity significantly.

    With its built-in ambient light options, the SUB10KEF provides ambient water color illumination approximately 2.5 times brighter than using physical blue filters. By covering two depth ranges—6–13 meters (20–43 feet) and 13–20 meters (43–66 feet)—at the twist of the rear dial, the SUB10KEF can be used in a variety of daytime lighting conditions as well as at night, when the 5600K (daylight) mode can be used.

    The SUB10KEF features an ergonomic 11-step (0–10) magnetic power control ring at the rear, and a rear-mounted LED display showing the brightness level as you turn the power control ring. After setting the brightness level, the display defaults, after five seconds, to the remaining burn time in minutes for the selected brightness level. The video light’s air-travel safe 72Wh battery pack can be charged from 0–80% in two hours and to 100% in three hours.

    Shipping late May, the SUBNOX SUB10KEF is priced at $800.

     



    PRODUCT INFORMATION

    SUB10KEF Wide Angle Video Light – 10,000 Lumens With Daylight 5600K & Ambient (BLUE) Water Colour

    The SUB10KEF is a compact 10,000 lumens (93 CRI) wide angle video light with the patented ability to switch between a daylight colour (5600K), and ambient water colours for 6–13m or 13–20m.

    Patented Light Head

    With the patented specially designed light head and COB, It does not require any physical blue filters to achieve this specially tuned ambient water colour illumination. This allows the torch to be used at various depths and lighting conditions night or day. (Ambient blue is not required for night dives).


    Power Control Ring

    The SUBNOX SUB10KEF utilizes a large 11 step (0-10) magnetic power control ring ergonomically located at the rear of the torch. This allows for smooth, effortless and intuitive control over the brightness level.

    The rear mounted power control ring is designed for one handed use in a single motion over a 180 degree turn of the ring. It is designed for easy use even with thick gloves. No more reaching over your torch to press buttons, or fiddling with tiny control knobs. Just grab and twist!

    Light Colour Selector & Power Switch

    The rear knob below the LED display allows users to switch between the 3 light options:

    • 5600 Kelvin (Daylight)
    • Ambient Blue (6–13m)
    • Ambient Blue (13–20m)

    The button at the center of this knob functions as the master switch for powering the SUB10KEF On or Off.


    LED Display

    The rear mounted LED display shows the brightness level as you turn the power control ring.

    Once the brightness level is set, the display will default after 5 seconds to the remaining burn time (battery level in minutes) for the brightness intensity chosen. A simple 4 bar battery icon is also displayed for all settings.

    3 different LED indicators display the current colour settings. 5600K, Ambient Blue (6–13m), Ambient Blue (13–20m).

    USB-C Rechargeable Battery

    The Battery pack for the SUB10KEF utilizes a fast charging USB-C controller that allows the battery to be charged from 0–80% within 2 hours (full charge from empty requires 2 hours 45 minutes) and is rated at an air-travel safe 72Wh.

    Scientists Find New Evidence That South Korea’s Female Freedivers Evolved for a Life Underwater


    Scientists Find New Evidence That South Korea’s Female Freedivers Evolved for a Life Underwater

    Haenyeo sing traditional songs before heading out to sea to harvest abalone, sea urchins, seaweed, and other seafood from the waters around Jeju Island, South Korea


    Scientists studying the DNA of the famous female freedivers of Jeju Island—the haenyeo—have discovered there are unique genetic differences that the women have evolved to cope with the physiological stress of freediving. Published in the scientific journal Cell Reports on May 2, 2025, the research was led by Melissa Ann Ilardo, a geneticist and assistant professor in biomedical informatics at the University of Utah.

    Ilardo and her colleagues recruited 30 haenyeo divers, 30 non-diving women from Jeju Island, and 31 women from the South Korean mainland for the study. The participants’ average age was 65. As well as sequencing their genomes from blood samples, the researchers compared their heart rates, blood pressure and spleen sizes. In order to simulate dives, participants held their breath while submerging their faces in cold water, stimulating the mammalian dive reflex. As a result, the heart rate slows, blood pressure increases and the spleen contracts.

    The analysis showed that the participants from Jeju—divers as well as non-divers—were more than four times more likely than the participants from the mainland to have a genetic variant associated with lower blood pressure. “Your blood pressure increases as you dive,” explains Ilardo. “Their [Jeju residents’] blood pressure increases less.” The scientists suggest that the genetic trait may have evolved to keep unborn babies safe—since the haenyeo dive throughout pregnancy, when high blood pressure can be dangerous.

    Previous research has linked cold and pain tolerance to another genetic variation, and this study revealed that the participants from Jeju were more likely to have this genetic variant. However, the researchers weren’t able to say with certainty whether the variant may be important for the haenyeo’s ability to dive throughout the year, since the participants’ ability to withstand low temperatures was not measured in the study.

    Genetics wasn’t the only factor to explain the haenyeo’s impressive diving capabilities. During the tests, the researchers also found a dramatic difference between the heart rates of the divers versus the non-divers. A reduced heart rate would help the haenyeo conserve oxygen during their dives. “Actually, their heart rate dropped about 50% more over the course of the dive than the control (participants),” says Ilardo. “We know that it’s because of training, because it’s something that we only saw in the haenyeo.”

    While much more work needs to be done, the research could potentially lead to the development of new drugs for lowering blood pressure.

  • David Attenborough Turns 99 and He Wants You to Fight for It

    David Attenborough Turns 99 and He Wants You to Fight for It



    May 8th is David Attenborough’s 99th birthday, and in his new documentary, Ocean, he’s marking the occasion with a veritable call to arms. “If we save the sea, we save our world,” says Sir David.

    Over the last seven decades, the beloved English presenter has made many films focused on our marine world, but this latest one is something different. Of course, there’s awe-inspiring cinematography aplenty, as you’d expect, but this time, the camera shows us the full extent of the tragedy occurring on the high seas today: The colorful reefs teeming with fish abruptly give way to vast deserts of broken, gray, lifeless coral—the aftermath of dragging huge nets along the ocean floor, killing everything in their path.

    “When I first saw the sea as a young boy, it was thought of as a vast wilderness to be tamed and mastered for the benefit of humanity,” says Attenborough in Ocean. “But now, as I approach the end of my life, we know the opposite is true.” Elsewhere, he admits: “After living for nearly 100 years on this planet, I now understand the most important place on Earth is not on land, but at sea.”

    While Sir David may have been criticized in the past for not doing enough to sound the alarm regarding the destruction of the natural world, in this documentary he doesn’t mince his words as he explains all the shocking ways we are harming our seas—with a particular emphasis on the blanket destruction caused by bottom trawling. Not only is he enraged that this practice is legal, but he’s also incensed by the fact that it is actively encouraged by governments through subsidies. “Three billion people rely on our ocean for food,” he points out in Ocean. “But ships sent by a few wealthy nations are starving coastal communities of the food source they have relied on for millennia. This is modern colonialism at sea.”

    Ultimately, though, Sir David is still hopeful. What he calls the “most remarkable discovery of all”—that the ocean can “recover faster than we had ever imagined”—has kept him from despair. He remembers a time, as a young man, when large-scale commercial whaling had all but wiped out our ocean’s largest inhabitants, but how—against all odds—a global powers bowed to public pressure and worked together to save the whales by enacting a moratorium on commercial whaling. In Ocean, he shows us places where conservation measures have been effective and marine life is thriving, and he’s optimistic about the global commitment to protect 30 percent of the world’s ocean by 2030, established at the 2022 UN Ocean Conference.

    At 99, Attenborough’s mellifluous voice is still strong: “It is my great hope that we all come to see the ocean, not as a dark and distant place with little relevance to our lives on land, but as the lifeblood of our home,” he says.

    Ocean is in cinemas from May 8th, and will stream on Disney+ on June 8th—UN World Oceans Day.
