Video: Meet Calypso, the predecessor to Nikon’s iconic underwater Nikonos cameras

03 Nov

A customer at Camera West in California recently traded in an interesting piece of photographic history, the Calypso underwater camera. The 35mm film camera was the first of its kind that didn’t need housing to be used underwater.

The Calypso was the brainchild of legendary explorer Jacques Cousteau and Belgian engineer Jean de Wouters. The Calypso was released in 1961 as the first 35mm underwater camera which could be used without housing. Cousteau wanted a small, simple camera you could use on land and underwater without any fuss.

When the Calypso launched, there were a trio of available lenses. Two of the lenses were manufactured by SOM Berthiot, 28mm and 35mm prime lenses. A third lens, a 45mm prime, was manufactured by Angenieux. In the video below, the Calypso is shown with the SOM Berthiot 35mm F3.5 lens. The knob on the left side of the lens barrel is used for focusing and the knob on the right controls the aperture.

The camera includes a distinct shutter design. When firing the shutter, the camera simultaneously winds the film. Since the camera is always ready to fire, there’s a shutter release lock on the top of the camera. The original camera strap is included and as you can see above, there is a built-in mechanism in the links to open the camera for loading film.

The camera’s construction is quite simple. Camera components are in the top portion of the body and the lower area is primarily a shell. The camera is constructed from an alloy and is coated in black enamel. Each component includes water sealing and the grip is faux sealskin. The camera’s top shutter speed is 1/1000s and it does include a port for using a flash.

To construct the camera, you put the two camera body components together and then mount the lens. Each lens includes a notch, allowing you to tell when the lens is fully mounted and sealed against water. At the time of its launch, the Calypso was rated to for use up to 200′ (60m) underwater.

In 1962, Nikon took over the production of the Calypso camera, rebranding it as the iconic Nikonos underwater 35mm camera. This was not Nikon’s first foray with underwater photography, as the Japanese company had already developed an underwater housing for the Nikon S2 camera in 1956. After teaming up with the Calypso’s original manufacturer, La Spirotechnique, the redeveloped Nikonos was released. Interestingly, in Nikon’s history of the Nikonos, Nikon says the camera was water pressure-resistant down to 50m rather than 60m, and the shutter speed topped out at 1/500s.

Ultimately, Nikon released three Nikonos cameras built upon the legacy of the Calypso, with the Nikonos III releasing in 1975. Nikon then went back to the drawing board and designed a full original Nikonos IV-A. This camera was released in 1980 and included new features such as a TTL exposure meter, aperture-priority AE control, an electronically controlled shutter, hinged open-and-close camera back and improved usability. The Nikonos V came next and was sold for 17 years before its discontinuation in October 2001. Nikon also released an autofocus underwater camera, the Nikonos RS AF, which could be used at depths of up to 100m. You can learn more about all the Nikonos cameras by clicking here.

2020 Underwater Tour Awards Winners

The Underwater Tour Awards recently announced the winners of its inaugural photography competition. Hundreds of images were submitted from around the world. Winning entries were selected by a panel of judges led by 6-time winner of the AIPP Professional Nature Photographer of the Year competition, Darren Jew.

The Guru Award, bestowed on the photographer who submitted at least 5 images, and had the best collection, went to Chelsea Haebich. An accompanying Q&A session is included with the 5 Guru images on display below. ‘I am still a few inches off the ground. I genuinely did not think I was in for a chance as I watched all the other amazing shots winning categories!’ exclaimed Haebich. ‘Winning this award might make me stop doubting myself and have a bit more faith in my abilities. Something I struggle with for sure.’

‘Moving forward I hope it can put my work out there further and bring people and connections into my life that will help me grow as a photographer and further share this astounding world with more people,’ Haebich continued. ‘I love seeing people’s curiosity and hearing their questions about the Underwater World. If winning lets me share that more, grow more and impact more people then that would be wonderful and very fulfilling.’

The next Underwater Tour and photography competition is set to commence May 13th, 2021.

Winner, Guru Award: Chelsea Haebich (Adelaide, Australia)

UTA: What was it that inspired you to take up nature photography?

CH: I came to diving somewhat later in life than most people and had never picked up a camera, but that first dive, nine years ago, under the Jetty at Rapid Bay in South Australia just blew my mind. I was inspired by the colors and the creatures. The variety and energy just astounded me.

I was so excited about what I saw and wanted to share it with anyone who would listen, but I found it so hard to convey what I was experiencing in words, so I grabbed a camera and never looked back! A little Panasonic point and shoot. Loved it. My long held fear of cameras went out the window pretty fast from there on, apart from Instructing, I hardly ever enter the water without a camera.

I feel compelled to capture what I see and feel, from the tiniest Clingfish, to the towering pylons of our local Jetties. I have always loved nature and animal interactions and now I feel inspired daily to capture that in images as best I can.

Winner, Guru Award: Chelsea Haebich (Adelaide, Australia)

UTA: How will winning the Underwater Tour Award help you moving forward?

CH: Personally, winning this award might make me stop doubting myself and have a bit more faith in my abilities. Something I struggle with for sure! Moving forward I hope it can put my work out there further and bring people and connections into my life that will help me grow as a photographer and further share this astounding world with more people.

I love seeing peoples curiosity and hearing their questions about the Underwater World. If winning lets me share that more, grow more and impact more people then that would be wonderful and very fulfilling.

Winner, Guru Award: Chelsea Haebich (Adelaide, Australia)

UTA: What do you consider your own challenges when taking photos?

CH: What do I consider my own challenges when taking photos (I was going to say something about the challenge of a permanently empty bank account, but I don’t think that is what you are looking for here in this question). Seriously, though, my challenges when taking photos is getting out of my comfort zone and experimenting more. I work a regular job full time and don’t get to dive as often as I like, so I want bang for my buck when I do.

I love to come home with new images to edit and explore and sometimes I don’t think I push myself and risk a card full of learning errors because I need to come home with something! So time would be the other challenge. I really have to push everything else aside to get the dive time I want, often neglecting other important life matters…which of course I can TOTALLY justify at the time.

Winner, Guru Award: Chelsea Haebich (Adelaide, Australia)

UTA: What is your aim when you’re taking images?

CH: My aim when taking images is to capture something about the animal or moment that makes people keep looking. With tiny creatures I love to capture the detail that often can’t see until I’m home looking at it on my computer. This draws me back to images to keep seeing detail. I really like to capture character and humor as well. Right or wrong I find many of the behaviors and habits of Marine creatures very comical and endearing. I love to capture character as it gives people something to relate to when they look at an image.

The image of the Australian Sea Lion is an example of that. The look it’s giving the camera conjures up images of peoples own puppies at home. Marine life is so often seen as cold and glassy eyed. I try and capture those personalities, or at least the personalities I see! I want people to connect and find something they love in a world they could never image themselves entering. I believe people will protect and look after things they love and understand better. So I guess my aim is connection, both for myself in the moment and for others when viewing the images.

Winner, Guru Award: Chelsea Haebich (Adelaide, Australia)

UTA: Do you have any preferred underwater subject or concept?

CH: I don’t have a preferred underwater subject or concept when I dive. Sometimes I have a goal or a shot in mind, but on the day I really like to just see what is presenting itself when I am down there. I don’t like to turn down opportunities with a critter or a shot just because I have a set goal. I really like to just let the world pass me by while I am down there and see what my eye picks up on.

I dive and set up my camera to the conditions we have here in South Australia and try to make the most of the day. Sometimes wide angle happens, but macro is more reliable here in SA. I don’t set out with any very set ideas. It’s part of what I love. I never know what I am going to come back with. It does mean you have to be on your toes with your settings and sometimes completely rethink what you are doing, but that all part of it for me. It helps me switch off.

Winner, Underwater Scenes: Pavlos Evangelidis (Brussels, Belgium)

Artist Statement: Leru Cut in Solomon Islands is one of my favorite dive sites. It goes under the island for about 100 meters at a depth up to 23 meters. It really comes alive when the sun is out and the sunrays break through the cracks but photography here can be challenging because of the extreme light conditions and the deep shadows.

Winner, Underwater Characters: Simone Caprodossi (Byron Bay, Australia)

Artist Statement: Northern Gannets fighting for a fish in Shetland Island UK.

Winner, Aquatic Abstracts: Louise Nott (Lane Cove, Australia)

Artist Statement: Pineapple Swirl, Sydney Harbour NSW.

Winner, Topside Scenes: Yung Sen Wu (Keelung City, Taiwan)

Artist Statement: These Pacific species of salmon will come to the west coast of Canada from the distant sea every autumn, return to the birthplace of the inland river through the estuary, and look for the estuary of the estuary, the temperature of the river, and the environment.

Winner, Underwater Black and White: Richard Condlyffe (Battle Creek, USA)

Artist Statement: Two Spotted Dolphins look as though they’re communicating and watching something out of shot. Bimini, Bahamas.

Winner, People’s Choice Awards: Pierre-Laurent Pablo (Nimes Languedoc, Philippines)

Artist Statement: Frog Fish hanging at Southern Leyte in Philippines.

Lomography’s new Analogue Aqua is an underwater ‘Simple Use’ film camera

30 Apr

Lomography has announced the release of the Analogue Aqua a new ‘simple use’ reloadable camera that comes packed an underwater case.

The Analogue Aqua is the latest version of Lomography’s take on the disposable 35mm film camera—this time with an aquatic twist thanks to its protective plastic housing, which is waterproof down to 10m (33ft).

The kit will be available in two versions, pre-loaded with one of two Lomography film stocks: Color Negative 400, for ‘classic analogue character’ or LomoChrome Purple for ‘violet tones that flourish and fade,’ in the words of Lomography. When you finish the 27-exposure pre-loaded film, you can put another roll in its place with the help of Lomography’s guide, giving you the convenience of a disposable camera with much less waste.

The camera itself operates on a single ‘AA’ battery, features a very rudimentary 31mm F9 lens, will focus on anything from beyond 1m (3ft) to infinity and has a permanent shutter speed of 1/120th of a second. In the event you need more light, the camera features a built-in flash that can fire once every 15 seconds.

Below are a few sample photos provided by Lomography:

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_5890969460″,”galleryId”:”5890969460″,”isEmbeddedWidget”:true,”selectedImageIndex”:0,”isMobile”:false}) });

The Lomography Analogue Aqua ‘Simple Use’ camera is available in both the Color Negative 400 and LoomChrome Purple versions starting today for $ 40 on Lomography’s online shop. The first units will ship out in May.

Diveroid housing turns your smartphone into a dive computer and underwater camera

22 Nov

A Kickstarter campaign has already gathered over ten times is funding goal for a campaign that aims to produce a smartphone dive camera system that uses your smartphone to take pictures as well as display live data about the dive itself.

Diveroid is an underwater housing kit that comes with a mini dive computer and a app that turn the users smartphone into an underwater camera while using the phones screen to display dive information and maintain a log of the dive. The housing accepts multiple models of smartphone and uses a set of three physical buttons to control the phone. The app connects to the mini dive monitor and the smartphone and displays depth, time and temperature information as well as guiding the diver around precautions such as avoid decompression.

The app takes over the phone’s camera function and offers ultra-wide-angle, wide-angle, zoom and selfie shooting modes, as well as options to record video. A red-filter effect can also be applied in the app to offer real-time preview and recording that compensates for the loss of red at certain depths.

The housing is said to be good for depths of 60m and keeps a track of your dive so it can tell you at what depths each picture was taken. Images can be overlaid with data graphs and the whole dive can be shared as a logbook through the app. When you need to summon a boat the app can send a text message with your exact location.

The campaign page shows the Diveroid kit with accessories attached for lighting the subject

The Diveroid kit is available for $ 249 via the Kickstarter campaign but will retail from $ 418 once it is in full production. The first units are expected to ship in February 2020. For more information see the Diveroid Kickstarter campaign page.


Disclaimer: Remember to do your research with any crowdfunding project. DPReview does its best to share only the projects that look legitimate and come from reliable creators, but as with any crowdfunded campaign, there’s always the risk of the product or service never coming to fruition.

News: Could This Sea-Thru Algorithm Be the Future of Underwater Photography?

18 Nov

The post News: Could This Sea-Thru Algorithm Be the Future of Underwater Photography? appeared first on Digital Photography School. It was authored by Jaymes Dempsey.

Underwater photographers may soon have a way of “removing water” from their photos, based on research done by Derya Akkaynak and Tali Treibitz at the University of Haifa (read report here).

As explained by Akkaynak and Treibitz, “An underwater photo is the equivalent of one taken in air, but covered in thick, colored fog.” And while the precise effects of water on images is somewhat technical, it doesn’t take much to recognize that water degrades images, causing a loss of both clarity and accurate color.

Enter Akkaynak’s Sea-thru algorithm, which is designed to remove color casts and other optical problems created by water. In other words, it can be applied to an underwater photo, one that’s blue (with inaccurate colors), and turn it into something that looks like it was taken on land.

For examples, check out the images in the Scientific American video:

??

How it works

But how was the algorithm actually developed, and how does it work?

Basically, Akkaynak took a series of underwater photos, making sure to place her color chart into the scene for an accurate reference. She ultimately compiled over a thousand images in several environments. From the reference images, Akkaynak and Treibitz developed a model that takes into account the unique ways that light interacts with water in order to correct underwater images for color and light.

Now, Akkaynak and Treibitz had academic purposes in mind when they conducted this research. The algorithm, as presented in the original research paper, is meant to “help boost underwater research at a time when our oceans are increasing stress from pollution, overfishing, and climate change,” by giving researchers better access to visual data from underwater cameras.

But it’s easy to see how the Sea-thru algorithm could be relevant to underwater photographers everywhere. If Sea-thru can make photos become more accurate and (often) more vivid and colorful, might underwater photographers like to use it on their own images?

On the other hand, there’s the question of whether the best underwater photos convey an authentic sense of the (underwater) environment. Without the blue tones of water and the haze that water provides, photos may lose the sense of wonder that comes from doing work under the sea.

So let me ask you: Do you prefer underwater images where the water is much less apparent? Or do you like more authentic underwater photos, color cast and all? Would you be interested in the Sea-thru software?

Tips for Doing Fine Art Underwater Bubble Photography

04 Nov

The post Tips for Doing Fine Art Underwater Bubble Photography appeared first on Digital Photography School. It was authored by Joanne Taylor.

tips-for-doing-underwater-bubble-photography

Doing underwater bubble photography is both fun and challenging! Read on for easy-to-follow techniques, tips, and tricks for you to try no matter which underwater environment you’re in!

underwater-bubble-photography

Safety

For your safety, have someone on land, in a boat or in the water with you to act as a spotter. Have them keep a floatation device with them at all times too. Underwater photography can be tiring, and you might feel the need for assistance from time to time.

Have drinking water accessible regardless of the weather. Be sure to have sunscreen on and beware of the sun reflections off the water: sunburns hurt!

underwater-bubble-photography

Equipment

There are many devices you can use, including a GoPro, underwater phones, and the disposable ones they sell at the drug store. However, the best way to achieve shots like these is to have an SLR camera within a professionally-made underwater housing. You can still try these types of shots with whichever device you do have, but it is easier to take them with a lot of control going in.

I achieved these shots with a Nikon D7100 and a custom Ikelite housing.

You can shop for professional underwater equipment from a variety of places, but Ikelite – www.ikelite.com has a strong reputation internationally, and for good reasons. You can also check out Mozaik Underwater Camera – www.housingcamera.com

Both websites sell camera and housing packages for underwater photography and also individual housing cases. You definitely want reliable, trustworthy equipment to achieve consistent, sharp images.

Equipment check

Please note that human error causes most floods (where water breaches the housing compartment, and you risk losing your camera and every photo you’ve taken). Common causes of floods are sand, hair, or dust in the O-ring (which you should lightly lubricate every so often) and improperly secured latches.

With a professional underwater housing, you have the same capabilities underwater as you do on land. This saves much time if you’re in deep water – no need to climb in and out of the boat or in and out from the beach. Same for scuba diving – sometimes coming up from a deeper depth is simply not an option. For those using other devices, be sure to know the depth limit of the device, or you risk losing everything!

Tips for Doing Fine Art Underwater Bubble Photography

Camera settings and taking the first few shots

Make sure the lens on both the camera and the housing is clean. There is nothing worse than getting underwater, taking some fantastic bubble photos, and then seeing a sunscreen finger smear in the corner of each shot.

In underwater photography, your body will be moving, so too is the water and the bubbles. So if in doubt, use your camera in Auto Mode the first few times. Alternatively, try setting your camera to F22 and F20 at 1/2000th, 1/4000th, and rely on natural light.

Next, you are ready to get into the water and don’t forget to defog your goggles before putting them on (spit or a defogging spray work great).

Bring your equipment in and determine if it’s working underwater with a few test shots (aim at your feet) and then check the image on your viewfinder. Make any adjustments necessary.

Tips for Doing Fine Art Underwater Bubble Photography

Water and weather

Take into consideration the appearance of the water. You are looking for water clarity. Sometimes, the bottom can be churned up by a recent storm, and there can be a lot of debris. Debris can cause low visibility and definitely with underwater photography, the clearer the water, the better.

If you are in a controlled setting such as a pool, the clarity of the water will depend on the chemicals added. If the water is cloudy due to improper chemical balance, there will be a hazy quality in all of the photographs.

The weather affects the light in your photographs. A cloudy day will allow you to use a flash if you have one. Only add a small amount of flash, or you run the risk of blowing out the bubbles entirely.

If you don’t have a flash, keep shallow and try taking photos in the top two feet or so as the light will only decrease the further down you go. If it’s raining, you can still take photographs. It is fun to get the water droplets falling on the surface of the water while bubbles are rising towards them.

When it’s a sunny day, light streams through the water surface and lights up the bubbles from behind. Try to take a few pictures with the sun in the shot as well.

underwater-bubble-photography

How to create bubbles with containers

Use a variety of containers for different sized bubbles. Try sand buckets, Tupperware, or other plastic bowls. Children’s stacking cups are great too, as long as they don’t have a hole or holes in the bottom. Anything can work (re-usable drinking bottles are great too) but avoid all breakables like glass.

Bring them one by one into the water, so they don’t float away. You would benefit from a helper to pass them to you, so it’s easier to juggle your camera and the buckets.

Start with the smallest, easiest to manage container, and work up to the largest as they are the hardest to maneuver underwater.

Take the container underwater by holding the opening directly over the surface and pushing it down underwater to catch the air inside. Practice tilting the cup slowly underwater to let the air trickle out in a trail of bubbles and practice tilting the cup quickly to let all the air out at one time.

Now take a few test shots of the air escaping the container. You might have to practice a few times not to catch your hand or the container in the shot.

Try taking the container deeper. Be patient until you get the right balance of speed of the bubbles versus shutter speed. Check your viewfinder and make any necessary adjustments regarding shutter speed, focal length, or the strength of your flash if you’re using one.

Tips for Doing Fine Art Underwater Bubble Photography

Try taking a series of images of bubbles using multi-shot (continuous shooting) for a better choice of images later.

Move into another section of the water for a variety of images. If you’re using the sun as a backlight, you may also have to angle your camera up towards the surface of the water to get a better shot.

How to create bubbles without containers

Take the containers out of the water and try kicking your feet and making lots of tiny bubbles.

Tips for Doing Fine Art Underwater Bubble Photography

Editing

Once you have downloaded your images, you are ready to edit.

Adobe Lightroom will make editing easy – though, you can use any editing software of your choice. Cropping will be your most used tool as you eliminate any hands, containers, or debris. Cropping is also necessary to zoom in on a section as you attempt to create the most aesthetically pleasing bubble photograph.

Tips for Doing Fine Art Underwater Bubble Photography

Occasionally, you may want to adjust the color of the photograph by making it bluer or taking all color away to see the bubble shapes in black and white.

Tips for Doing Fine Art Underwater Bubble Photography

Conclusion

Fine art underwater bubble photography takes a lot of patience, so relax and have fun. Bubbles are fragile, finite, and often hard to predict. Your best shots may be a string of bubbles, a cloud of little ones, or a single, large one.

Let’s see what you can do! Please share your underwater bubble photography with us in the comments!

Thoughts and Field Test: Leica X-U Underwater Camera

14 Oct

The post Thoughts and Field Test: Leica X-U Underwater Camera appeared first on Digital Photography School. It was authored by Suzi Pratt.

leica-x-u-underwater-camera-review

When it comes to waterproof cameras, you’re likely to think of GoPro or a similar action camera first. But what if you wanted a waterproof camera with full manual control? There aren’t many options on the market unless you’re willing to splurge for an underwater housing for a DSLR or mirrorless camera. But there’s a less-known option made by the venerable camera brand, Leica. In 2016, Leica introduced the Leica X-U – a rugged, waterproof compact camera. It didn’t seem to get much fanfare as it was completely unbeknownst to me until I browsed Borrowlenses.com in search of a camera for my upcoming whitewater rafting trip.

So how did it perform? Read on to find out!

Leica XU underwater camera

Technical specs

The Leica X-U is considered a point and shoot camera. It has a 16.2 megapixel APS-C CMOS sensor and a fixed Summilux 23mm f/1.7 lens (equivalent to about 35mm in 35mm format). The camera can shoot both RAW and JPG photos and record full HD video (1080p).

Some dials allow you to take full manual control of the camera and set the ISO, shutter speed, and aperture. You can even manually focus the lens.

Taking into consideration all of these specs, this is essentially a pro-level camera that has the added benefit of being dustproof, shatterproof, waterproof (up to 15 meters for 60 minutes), and shockproof (from heights of up to 1.22 meters). It has a pro-grade camera price tag retailing at $ 2,999 USD.

Look and feel

There’s no escaping the fact that the Leica X-U is a chunky camera, especially when compared to other waterproof point-and-shoots on the market. It weighs in at 1.32 lbs and doesn’t float or come with a floating strap. Thus, you’ll want to make sure it is always strapped tight to you, or find a floating strap for it.

The camera exterior, made of anti-slip rubber, feels good in the hands. In front is a manual focus fixed lens with a built-in flash on top. There’s also a hot shoe on top of the camera for adding a larger flash or extra accessories.

Leica also includes a rubber lens cap with a small strap, but it fits very loosely and is prone to falling off. I recommend looping the lens cap strap to the camera for extra security.

Leica XU underwater camera

Ease of use

This was my first time using a Leica camera. Up until this point, all I knew about Leicas was that 1) they were expensive, 2) they’re very solid in construction, and 3) their user interface is relatively simple and straightforward. All of these assumptions are true in the Leica X-U, but it is the third point that I appreciated the most.

The bulk of the camera’s controls are in the top two knobs and the lens’ focus ring. If you’ve used a film camera or Fujifilm mirrorless camera, you’ll feel right at home. Any other camera settings are controlled using buttons on the rear end of the camera, where there is also a large, brightly-lit LCD screen. Buttons were decently responsive, and the LCD was fast and accurate.

The one thing I wish Leica included is a touchscreen LCD. Menus are laid out simply, and it was easy to adjust settings. A rechargeable battery powers the camera, and it easily lasted a full day of shooting.

Leica XU underwater camera

Performance in the field

I extensively researched this camera before renting it for my rafting trip. Unfortunately, most of the camera reviews swayed toward the negative. Many claim the Leica X-U’s autofocus is too slow, and its overall features fall behind when compared to what modern cameras (and smartphones) can achieve.

When shooting with this camera, I brushed off those negative reviews. Shooting with this camera was an absolute joy. I loved the ability to shoot in manual without having to worry about water splashes. And it is very easy to go from shooting still photos to video since the video record button is right next to the shutter.

Leica-X-U-underwater-camera

Best of all was the ability to shoot photos of the night stars, which was my main reason for wanting this camera. My rafting trip frowned upon bringing non-waterproof cameras, so I didn’t want to risk bringing my expensive mirrorless cameras.

However, we would be spending the night in the pitch-black forests of Southern Oregon with stars shining bright every night, and I wanted the ability to snap photos of them.

With its fast aperture and the ability to shoot in manual focus, the Leica X-U had the capability of pulling off star photography, and it did so pretty well.

Leica XU Underwater Camera

At the end of each day, I reviewed the photos and videos on the camera and marveled at what I was able to capture. Those negative reviews seemed completely wrong – that is until I reviewed everything on my computer.

Image and video quality

It’s a classic mistake to review media content on a tiny device screen and think that everything is working well. The real quality test is to review them on a big screen. Doing this showed that those reviewers were 100% right.

The Leica X-U’s image quality is quite good when shooting a static or slow-moving object. However, the camera absolutely blew the autofocus when shooting anything in movement.

This is an odd shortcoming for a camera that seems built for action, but it happened on a very consistent basis.

Leica XU Underwater Camera

For fast-paced scenarios, the autofocus simply wasn’t fast enough, leading to many unfocused shots like this.

Leica XU Underwater Camera

The video quality was downright atrocious, and I’m ashamed that I put so much trust in this camera when shooting videos. My Samsung Galaxy S10, in its waterproof case, took far better video.

So…should you use this camera?

Handling this camera was an absolute joy, but I can’t commend its photo or video quality.

If you’re seeking a waterproof camera with manual controls, this camera might work for you, but it depends on what you’re shooting. In fast-paced action scenarios, this camera’s autofocus performance won’t keep up. But if you’re shooting static landscapes or astrophotography, this camera will likely meet your needs.

For videography, don’t even bother.

CHASING DORY is a portable, affordable underwater drone with 1080p video

06 Oct

If there’s one omnipresent trend in the drone industry, it’s this: manufacturers are thinking smaller. Companies are aiming to make unmanned aerial vehicles more compact while inserting as many premium features, found in their larger counterparts, as possible. The CHASING DORY underwater drone, which is currently in the midst of a successful crowdfunding campaign on Kickstarter, is no exception.

Presumably named after the daffy but lovable fish from the movie Finding Nemo, at 18.8cm (7.4in) wide, the drone is smaller than a standard sheet of paper. It is the follow up to Shenzhen-based company CHASING’s GLADIUS MINI drone whose 2017 Indiegogo campaign ended with 1629% funding and a 100% delivery rate to backers. DORY is 56% lighter and 65% smaller than its predecessor which weighed 2.5kg (5.5 pounds).

An algorithm ensures photos remain vivid in all conditions.

DORY’s camera has an F1.6 lens with 1/2.9″ CMOS sensor capable of recording at 1080p, a 100° field of view, and a ±45° Tilt-Lock mode that allows you to scan the floor of a body of water or view its surface above. Two 250-lumen lights placed on the front of drone illuminate the area where its operating without overwhelming underwater inhabitants. CHASING’s color-restore algorithm keeps photos vivid in all conditions. 8 GB of internal memory means you don’t have to worry about losing any footage.

The lowest possible pledge available on Kickstarter will get you a DORY underwater drone, Wi-Fi buoy, tether, and charger. The Wi-Fi buoy helps your mobile device stay connected up to 15 meters (49 feet) away with the wired tether. An Anti-lost Warning is there to prevent any chance of getting disconnected. Depth Lock helps the drone remain stable so it doesn’t get tossed around. The charger takes two hours to power a 4800 mAh battery which will give you one hour of operating time. Unlike other underwater drones that require multiple components to be charged, only the drone needs it with the DORY.

DORY doesn’t come with a remote. Instead, a smartphone is all that is needed, along with the CHASING DORY app (available for iOS and Android), to control the drone. You can customize imagery with 19 different filters, share footage on social networks including Facebook and Instagram, and even stream live. The app also features Co-Play which enables one person to maneuver the drone while the other controls the camera.

As of this writing, there are 17 days left to back DORY on Kickstarter. The campaign has already raised over $ 120,000 of its initial $ 30,000 goal. If underwater exploration is your interest, this portable, affordable drone is an option worth considering.


Disclaimer: Remember to do your research with any crowdfunding project. DPReview does its best to share only the projects that look legitimate and come from reliable creators, but as with any crowdfunded campaign, there’s always the risk of the product or service never coming to fruition.

Apple patent application details tech to improve mobile underwater photography

29 Mar

Underwater photographers and cameras have to deal with less than ideal conditions. Light levels are low, water can be murky and add color casts to your images. Underwater modes on rugged cameras and (waterproof) smartphones are not new but now a patent application filed by Apple suggests mobile users could soon benefit from a more sophisticated version and achieve better underwater imaging results in the future if the system is ever implemented.

Apple’s patent application is titled ‘Submersible Electronic Devices with Imaging Capabilities and describes a system that automatically detects when the shutter button is pressed under water and makes the necessary adjustments to optimize image quality.

The device uses a range of sensors to detect if it is underwater and determines what steps are required to improve image results. A color ambient light sensor could be used to measure ambient light spectra above and under water and help calculate how much light is absorbed by the water. Depth, distance, pressure, and orientation sensors can be deployed to measure the water´s murkiness as well as the distances to the surface and subject. Backscattered light could be measured as well to find out how it affects the image.

With the data from all sensors collected, the system would then make adequate adjustments to camera settings and image processing, for example modify the white balance to avoid greenish color casts, or enhance exposure and texture rendition on the subject in murky conditions with low visibility.

As usual, there is no way of knowing if the patent ever makes it into a final product but given most of the sensors mentioned in the document are already present in current iPhone models, the system could probably be pretty easily implemented via a software update.
