Behind the scenes of Drew Gardner’s gigapixel shot of British royal family

16 Jun
Drew’s 2.3 gigapixel image is made up of more than 100 50MP files, shot with the Fujifilm GFX 50S. Click the thumbnail to launch the interactive image at www.telegraph.co.uk

Photographer Drew Gardner has been a photographer for more than 30 years, and since 1999 he’s worked mostly in the commercial world. Following a recent move into 360-degree imaging, he accepted a commission from British newspaper The Telegraph to shoot a gigapixel image of the queen’s birthday parade. Earlier this week we spoke to Drew to learn more about how the project came together.


Following a career working in local and national press, I decided to move away from newspapers and into commercial and advertising photography, in 1999. These days I shoot extensively for magazines around the world, so the commission has to be something really special to entice me to work with newspapers again.

When I was asked to shoot a gigapixel photo for the Daily Telegraph, it was a trip down memory lane for me in many ways, but with the latest technology so I leapt at the chance. I was approached about two weeks before the event, and I spent many hours working out the sequence of events and the best position to place the camera.

I work with a wide variety of gear but this occasion seemed a perfect opportunity for a medium format camera, where ultimate resolution would be very useful.

‘The final image doesn’t represent one moment, but rather many different moments’

I like shooting gigapixel photos to record events. The final image doesn’t represent one moment, but rather many different moments. This provides a better overall feel of what it was like to be there. When I say many different moments, the final gigapixel image is made up of more than 110 50 megapixel images, shot on a Fujifilm GFX 50s with a 250mm F4 lens. The result is a 2.3 gigapixel file.

Drew Gardner has been a professional photographer since 1979. Based in the UK, Drew’s work spans local and national press, and commercial photography for clients including Manfrotto and Suzuki Motor Corporation.

I love the Fujifilm GFX 50S. It really suits the way I shoot medium format camera, and it weighs less than most DSLRs. Image quality is stunning and it has proven very reliable.

What I really like about the GFX is its high ISO performance. Even though the light was excellent I shot at ISO 1600 to allow me to stop down to F11-16 for better depth-of-field. To move the camera I used a Seitz VR drive motorized head – the same head that I use for all my 360 degree still images, too.

I’m a huge fan of Brian Storm of Mediastorm who is a great advocate of the use of audio and this was the perfect occasion to record ambient audio of the event with a Zoom H2N audio recorder. Audio is all too often overlooked and yet it is a very easy way of adding another valuable dimension to a gigapixel or 360 panorama image.

Behind the scenes: Shooting a documentary atop a moving train

22 May

From 2015 to 2017, filmmaker Miguel de Olaso (AKA Macgregor) and his crew spend many months traveling back and forth on the famed Mauritanian Railway—one of the longest and heaviest trains in the world, the so-called ‘Backbone of the Sahara—to document the grueling journey endured by merchants who regularly travel atop this train to transport goods to people living in remote Saharan towns.

The result is a beautifully-executed 12-minute documentary titled The Mauritania Railway: Backbone of the Sahara, which follows the journey of Malick: a 27 year-old merchant who relies on the train for his livelihood, even as he risks death each time he climbs aboard.

The short doc was shot entirely on a Sony F35 that was modified to take Nikon lenses (for reasons you’ll understand in a moment), and filming the documentary was a grueling process. We spoke with Macgregor shortly before the documentary was released last week, and he shared some details about the kit he used, the challenges he faced, and why he would never ever do this again.

The Mauritania Railway

by Macgregor

My crew and I put ourselves in the shoes of one of these merchants (over a two year period) and filmed the journey they go through on a daily basis. The result is a cinematic and immersive glimpse into a way of life that exists nowhere else in the world.

I shot the entire documentary on a Sony F35, Not sure how much you know about this “old” digital cinema cameras. The F35 was the successor of the Panavision Genesis, which was a big, heavy beast. But after the arrival of the solid state recorders a few years ago, the F35 became pretty compact and lightweight given the image quality it provided. Still not a DSLR in terms of size, but comparable to an Alexa for a fraction of the cost and size.

Anyways, even though I owned a set of PL mount lenses, I didn’t want to get them ruined in the desert sands of Mauritania so I decided to modify my Sony F35 with a custom built Nikon mount. That would let me travel lighter and use way cheaper glass than PL, but still capture a super high-quality image. We needed to travel with all our gear for more than a month and be able to move fast. Would a DSLR or Canon C300 had been a better choice? Possibly, but this project had to look amazing and I did not want to compromise on image quality. This had to look like a feature, shot on real locations and with real people.

Of course not all the lenses made it back home, but the camera did and it’s still working to this day.

This was a passion project that we did for the fun of it. But shooting atop of this damn train was horrible, dusty, endless, painful… I wouldn’t recommend it to anyone. It might all look very pretty with nice music, etc. but oh man, after three trips I said I’m not doing this again. Of course, we did end up going back and shooting more footage… #filmmakerlife

Behind the scenes of Himalaya Bound: Images of nomads in north India

24 Apr
17-year-old Mariam leads her family’s caravan through the foothills of the Himalayas, while carrying her 2-year-old niece in the blue plaid shawl over her shoulders.

The forests and mountains of north India are home to a unique nomadic tribe whose world revolves around caring for the water buffaloes that they herd. During the fall and winter months, the Van Gujjars dwell in the lowland jungles of the Shivalik Hills, where thick foliage provides plenty of fodder for their animals at that time of year. But by mid-April, as temperatures there soar above 110 degrees, the leaves and grasses wither and die and creeks and streams run dry. With nothing left for their buffaloes to eat or drink, the Van Gujjars must move elsewhere.

Entire families, from infants to the elderly, trek with their herds up into the Himalayas, where melting snows reveal lush alpine meadows laced by gurgling streams, which provide abundant grass and water throughout the summer. When the cold sets in at the end of September, they head back down to the Shivaliks, where the jungle has sprung back to life following the monsoon rains. The tribe has followed this cycle of seasonal migration—up in summer, down in winter, perpetually living in the wilderness and shunning settled village life—for over 1,500 years.

My most recent book, Himalaya Bound: One Family’s Quest to Save Their Animals – And an Ancient Way of Life, which was published by Pegasus Books earlier this year, follows one extended Van Gujjar family on their spring migration into the mountains. In this article, I’ll delve into the story behind the images that are featured in the book’s photo insert, which is sandwiched between 230 pages of text.

Who Am I?

I’m a freelance photographer and writer for magazines and newspapers, including The New York Times. I’m also the author of three books.

I often find myself drawn to stories about nomadic communities around the world—for my first book, Men Of Salt: Crossing the Sahara on the Caravan of White Gold, I traveled 1,000 miles over age-old trade routes north of Timbuktu with one of the last working camel caravans on Earth. I’ve spent time with nomadic / transhumant people in Africa, the Middle East, a number of states in India, as well as Mongolia and the Southwestern U.S.

Before taking on the project that became Himalaya Bound, I had dreamed of migrating with a tribe—partly to document what is becoming an increasingly rare way of life, and partly because I imagined it would be an amazing thing to experience.

The Van Gujjars’ livelihoods are based almost entirely on the sale of buffalo milk

Planning

No, I did not fly over to India, wander into the jungle, and start randomly knocking on huts asking Van Gujjars if I could migrate with them. As the idea for this project began to crystallize in my mind, it seemed wise to investigate how realistic it was to pursue before channeling too much time, money, and energy in its direction.

My first step was emailing the director of the Society for the Preservation of Himalayan Indigenous Activities (SOPHIA)—a small non-profit organization based in Dehradun, India, that advocates for the tribe—asking if he thought it would be possible for me to travel with a nomadic family and document their migration from beginning to end. He replied that he would check in with a few Van Gujjars to see if they were open to the idea. As it turned out, they were; since they were being pressured by the government to abandon their way of life against their will, they thought it might be helpful if someone would share their story with the rest of the world. SOPHIA also connected me with a translator who was willing to join me for most of the journey.

Gear

My choice of camera gear was determined by three factors: weight, budget, and year. The year was 2009 and I had to watch what I spent. But my main consideration was the fact that I was embarking on an assignment during which I would be trekking for over a month, from the lowlands into the Himalayas, while hauling everything I needed on my back—including a sleeping bag, clothing appropriate for temperatures ranging from over 110 degrees to below freezing, a first aid kit, and more. Thus, my goal was to make the most out of as little camera gear as I could carry and still get satisfying images.

I ended up taking a Nikon D90 (remember the year) with a few Nikon lenses: an 18-70mm zoom, plus 50mm F1.4 and 35mm F1.8 primes. I kept my old Nikon D70 in the bottom of my bag as a backup in case the D90 failed (it never did), and I brought along a low-quality but very lightweight tripod. Knowing that I might spend days or weeks without an electrical outlet, I also carried a bunch of batteries.

The prime lenses proved to be crucial: many days, we hit the trail by 3am, aiming to arrive at our next camp as early in the morning as possible. This meant that my best shooting opportunities on the trail were often during the liminal hours in weak light around the break of dawn. With the caravan marching forward, I had to get shutter speeds fast enough to stop motion, and the only way to do that was with wide apertures—often shooting at F2. Carrying my fully loaded backpack, I would run ahead of the family, pause, turn, shoot, and repeat, as they quickly caught up to me.

Getting the Images

The most important element in the series of images I returned with was the time I spent deep in the Van Gujjars’ world. I lived with them for forty-four days: walking with them, herding buffaloes with them, swimming in rivers with them, joking around with them, helping with daily chores, and sleeping under their tents. I formed real relationships with my companions, which I think accounts for how natural they appear and how clearly their personalities are communicated through the images.

I never set up shots or posed anyone—I either snapped away while they were doing whatever they happened to be doing or, for true portraits, they presented themselves however they liked.

The heads of four Van Gujjar families discuss their strategy for moving higher into the Himalayas, after the government has threatened to ban them from their ancestral alpine meadows, where they have gone each summer for generations, because those meadows are now within a national park. They scrambled to find a different place to spend the summer.
Jamila cooks lunch on the trail, with her 2-year-old son Yasin on her lap.
Mustooq and his little cousins, Bashi and Salma, asked for their picture to be taken.
Dhumman, the father of the family I traveled with, wanted a photo with his favorite buffalo.

Of course, the time I spent immersed with the tribe also allowed me to witness—and shoot—the scenarios that were essential to telling their story, as they happened.

One part of the Van Gujjars’ culture that I needed to capture was the deeply personal connection that they have with their water buffaloes. They think of their large horned animals as family members, and readily sacrifice their own comfort for their herds. If a buffalo falls ill, Van Gujjars become wracked with concern; if one dies, they mourn for it as though it were human. They never eat their buffaloes nor sell them for slaughter, using them only for the milk that they produce. (Though they are Muslim, Van Gujjars are also traditionally vegetarian, averse to the idea of killing animals.)

In order to get photos that convey this relationship in a way that was organic and authentic and not staged, I had to be there during those moments when that kind of closeness was demonstrated, and my companions had to be comfortable enough with me around so the fact that a foreigner with a camera was taking pictures didn’t alter the moment for them.

Goku pets one of her family’s buffaloes, at about 10,500’ above sea level.
Sharafat dries off after a swim in the Yamuna River, trusting a buffalo enough to use it as a lounge chair.
Karim gets his milk straight from the source.
Bashi watches the herd at a camp in the mountains.

In the course of documenting the migration, unexpected issues arose. While covering the human rights aspect of the story, I learned that the government was threatening to ban a number of Van Gujjar families—including the one that I was traveling with—from their ancestral alpine meadows, where they had spent summers for many generations. Those meadows had been absorbed into a national park, and park authorities didn’t want the nomads using them any longer. The Forest Department announced that any Van Gujjars who entered the park would be arrested and have their herds seized—while refusing to offer them any alternative pastures.

This left these families deeply shaken, facing dire circumstances, because they had no idea where they would take their buffaloes for the season. Hence, when the father of the family I was with joined about 80 of his fellow tribespeople at Forest Department headquarters in Dehradun (about two hours by bus from where we were camped) to plead with park officials to let them go to their traditional pastures, I went to take pictures.

Though I did nothing more than photograph what was a very peaceful scene, the park director had me arrested for being a “foreign political agitator,” and when I objected I was forced into a police car at gunpoint. Fortunately, no one thought to demand my memory cards, and the captain at the police station released me relatively quickly, realizing that the charge was absurd. What could have been a nightmare turned into a gift: by the time I rejoined the Van Gujjars that night, word about the incident had spread among the tribe, so even people I hadn’t yet met trusted me by my reputation, knowing that I had been pushed around by the same person who was pushing them around.

Weeks later, another episode posed a photographic dilemma for me. While camped at about 10,000 feet above sea level, a cataclysmic Himalayan storm struck, during which a tree washed over a cliff and landed on several young buffaloes, crushing one’s front left leg. A broken bone stuck out of the yearling’s flesh and the hoof below it flopped around like it was attached by a rubber band. It was bad, really bad, and because of how close they feel to their animals, everyone in the family was devastated—even the men were weeping.

Watching this unfold, part of me was aching to take pictures of this scene. But another part of me felt that in this moment of raw anguish, it could be the wrong thing to do: that the snapping of a shutter could create a self-consciousness that would inhibit my companions’ experience and their expressions of suffering and vulnerability.

Bashi comforts the yearling with the broken leg

I vividly remember a photograph that once appeared on the front page of a major American newspaper, probably twenty years ago or so: it was taken at a funeral, I believe in England, after some horrible tragedy. I don’t recall the specific circumstances—what stood out to me was that one of the graveside mourners depicted in the image was looking at the camera dead-on, and using her fully extended middle finger either to wipe a tear, or to convey a not-so-subtle message to the photographer. It was hard not to imagine it was the latter.

I think it matters how taking someone’s picture makes them feel, and I try to weigh how important it is to get any one image if the taking of that image might be hurtful or disrespectful in some way. There are an array of factors to consider in what can be a split-second decision, but I do think it’s worth questioning how many photos the world needs of grieving people in tears. Surely we need some, but how often do those photos serve a larger purpose—such as provoking outcry against genocide or bringing aid to famine victims or filling in a crucial piece of an important story—and how often might those images be, say, a photojournalistic cliché?

In the particular dilemma that I faced, I decided the world’s need for photos of this family in their moment of distress was outweighed by what I perceived to be the family’s need to freely express their feelings without a camera clicking around them. I felt as though shooting right then would have been greedy—as though I would have been willing to make people I cared about feel uncomfortable so I could return with a photo of their suffering. I kept my lens cap on until a semblance of composure returned, hoping that perhaps there is some kind of photographer’s karma, which would reward me with even better shooting opportunities for letting this one pass by.

I don’t claim any moral high ground for making that choice. It was simply the right choice for me, in that moment. I’ve talked to a number of photographers who adamantly disagree with my decision, and I understand and respect their opinions even if I don’t share them. Of course, since I’m a writer as well as a photographer, I knew that I could always write about the scene later, creating a deeply moving image with words, thus telling the story without disturbing the moment as it was happening. And a couple of days later, I felt like I did receive a bit of the photographic-karmic reward I’d hoped for.

The family decided to save the yearling, splinting its leg and carrying it up and over a 3000-foot-tall Himalayan pass to the meadow where they would spend the summer.
This was one of the most incredible things I’ve ever seen. And they did it not because the animal was worth much money, but because they love their buffaloes and would never leave one behind if there was any chance of saving it.

After the Migration

I’ve been back to visit the family I traveled with a few times over the years since the migration. Once, I was lucky enough to catch them on their way back down from the Himalayas, and was able to join them for a few days on the road.

Though I had given them many prints of the pictures I took, it wasn’t until 2016 that any Van Gujjars got a real taste of what I was doing with this story. That year, a set of my photos from the migration was exhibited in New Delhi at the Indira Gandhi National Centre for the Arts, and I gave a slide show at the opening. A few people from the tribe had been invited to attend, and though none of my companions were able to come, some of their cousins did.

The presentation was translated into Hindi as I gave it, and afterwards one of the Van Gujjars asked for the microphone and told the audience, “This is our life!” saying he was very happy that their story was being told. It was the most satisfying form of validation that my work on this project could have received.

Video: The story behind Canon’s crazy 50-1000mm CINE-SERVO lens

06 Apr

This short video released by Canon USA just a couple of days ago tells the story behind one of Canon’s most impressive optical achievements: the $ 78,000 Canon CINE-SERVO 50-1000mm T5.0-8.9 CN20x 50 IAS H/P1 lens introduced in 2014. We don’t cover much broadcast equipment here on DPReview, but even we couldn’t help taking note of this impressive lens when it was first announced.

As Canon USA Senior Fellow Larry Thorpe explains in the video, this lens was the result of a challenge posed to Canon by wildlife filmmaker Ivo Nörenberg in 2010. Nörenberg asked Canon to produce a long zoom 4K Super 35mm lens that would allow him to capture a seemingly impossible zoom range.

Zoomed all the way in, Nörenberg needed this lens to be able to “fully frame a subject of 4-5 feet (1.2-1.5 meters) in height from a distance of 300-350 feet.” Then, without changing lenses, he wanted to zoom back out and capture “great outdoor vistas.” And as if that’s not difficult enough, Nörenberg also asked Canon to keep the lens size manageable: no more than 15lbs (~6.8Kg) and no longer than 16 inches (~40cm).

It took four years, but this is what Canon came up with:

It wasn’t easy. Thorpe calls this lens “the most challenging project ever undertaken by the Canon optical design team.” But in the end, Nörenberg says Canon delivered 100% of his specifications and ideas. Not only that, Canon also built a 1.5x teleconverter right into the lens, giving the CINE-SERVO lens an extended range of 50-1500mm.

Check out the full video above to hear the story from Thorpe and see the lens in action capturing footage of wolves in arctic Canada, only 1,000Km (~620 miles) away from the North Pole.

Samsung explains the sensor tech behind the Galaxy S9’s super-slow-motion mode

05 Apr

Samsung published a couple of technical blog posts today, providing some detail on the stacked sensor technology used in the new Galaxy S9 and S9 Plus smartphones, and specifically how this tech is used to power the devices’ super-slow-motion mode.

This mode can record 960 frames per second at HD resolution for a duration of 0.2 seconds, which translates into 6 seconds playback time at 30 fps—32 times slower than standard video. The resulting videos can be reversed, exported as GIFs and edited in other ways.

To achieve the blistering fast frame rates, Samsung has adopted similar imaging technology to what we’ve previously seen on some Sony devices. The S9 sensor offers faster sensor readout-times, bandwidth and video processing of the application sensor than on previous Galaxy generations by using a three-layer stacked sensor design that consists of the CMOS image sensor itself, a 4x faster readout circuit, and a dedicated DRAM memory chip for buffering:

In addition to slow-motion, the stacked sensor helps reduce rolling shutter effects in video mode, and counter camera shake through frame-stacking methodologies.

“We were able to achieve a readout speed that is four times faster than conventional cameras thanks to a three-layer stacked image sensor that includes the CMOS image sensor itself, a fast readout circuit, and a dedicated dynamic random-access (DRAM) memory chip, which previously was not added to image sensors,” explained Dongsoo Kim. “Integrating DRAM allowed us to overcome obstacles such as speed limits between the sensor and application processor (AP) in a high-speed camera with 960fps features.”

You can see some of the Samsung super-slow-motion video results in the video below. Samsung’s article on the technology is available on its blog, where you’ll also find an interview with the team behind the new sensor.

Behind the scenes with some incredible camera robots

05 Apr

Tech YouTuber Marques Brownlee of MKBHD recently took a trip to Portland, OR to meet up with the team behind Motorized Precision and show off some of the incredible camera robots they’ve built. The resulting behind the scenes videos show you why these robots exist, and the kinds of shots they’re able to get that are just plain impossible for a human to recreate with the tools we currently have available.

Forget stabilizers and dollies and tracks and sliders, a human would have a very hard time capturing a shot like this:

Which was done like this:

You might recognize this robot and its CGI-like moves from the commercial that introduced Microsoft’s Surface Studio to the world. Anything that wasn’t CGI or visual effects in that commercial was shot using the KIRA robot:

Brownlee and the team at Motorized Precision set up several example shots using both the KIRA—MP’s most powerful and capable robot—and the smaller MIA. Both of these are controlled by a piece of software called MP Studio, which also allows you to manipulate the robot using an XBox controller, something Brownlee also demos.

Check out the full ‘Dope Tech’ video at the top to see more interesting behind-the-scenes shots.

Huawei P20 Pro hands-on: 3x zoom lens leaves the competition behind

04 Apr

The P20 Pro is Huawei’s latest flagship smartphone and, at least in the camera department, arguably the most innovative mobile device we have seen in quite some time. The camera module was developed in cooperation with Leica and is the first to combine three sensor/lens modules:

  • A large 1/1.7-inch RGB sensor with Quad-Bayer structure in the main camera is designed to capture as much light as possible and keep noise levels low.
  • A secondary high-resolution monochrome sensor provides depth estimation for the simulated bokeh effect, helps with digital zooming at low magnifications and improves detail and noise levels.
  • A dedicated tele-camera with an equivalent focal range of 80mm springs into action at 3x or higher zoom factors.
The Huawei P20 Pro camera combines three cameras: The main module is at the center, the monochrome camera at the bottom (left in this image) and the tele at the top (right).

So the spec sheet looks impressive but is the Huawei P20 Pro the best camera smartphone money can currently buy? We had the opportunity to shoot with a Huawei P20 Pro for a few days. Here are our first impressions.

Please note that the camera software on our test unit is not final, so some improvements can be expected for the production version.

Key specifications:

  • Triple-camera, 10MP output size
  • Main camera: 1/1.7-inch 40MP Quad-Bayer sensor, F1.8 aperture and 27mm equivalent focal length
  • Secondary camera: 20MP 1/2.78-inch monochrome sensor, F1.6-aperture and 27mm equivalent focal length
  • Tele-camera: 8MP, 1/4.4-inch RGB sensor, F2.4-aperture, 80mm equivalent focal length and optical image stabilization
  • Kirin 970 chipset
  • 6.1-inch Full View display
  • 6GB RAM
  • 128GB internal storage
  • 4,000 mAh battery

Wide-angle

In bright light the P20 Pro’s main camera captures images with good detail and very low noise levels. As you can see in the sample below, there is no noticeable grain in the blue sky, which is unusual for a smartphone, and fine detail is rendered nicely, though almost a touch oversharpened. Dynamic range is excellent as well, with very little highlight clipping for a smartphone camera.

Colors and contrast are definitely on the vibrant end of the scale but if you like things a little more natural you can can set colors to ‘smooth’ in the settings. There is a touch of corner-softness in our sample but overall the P20 Pro performs very well in good light.

ISO 50

The picture below was taken in a dim bar. In these conditions the camera does a very good job at keeping noise levels down. Some fine grain is noticeable in the shadows, but overall the image is very clean.

Some detail is lost on very fine textures but you have to zoom in to full-size view to notice. Edge detail is still very sharp and colors are maintained nicely. This is very good image quality from a smartphone in these light conditions.

ISO 1250

The very dim street lighting in the scene below pushes the P20 Pro camera to its limits. The image is exposed very well and colors are rendered nicely. However, detail clearly suffers and some fine textures are very soft. In these conditions the lack of optical image stabilization also becomes obvious, with some images showing signs of camera shake.

ISO 4000

Zoom

Thanks to the triple-camera with dedicated tele module, zoom is one of the P20 Pro’s highlight features. The series below shows the same scene as the first image in this article, with the camera zoomed onto the stork that is nesting on the church tower.

3x zoom

As you can see when clicking through to the full version of these images, detail is still decent at a 3x zoom factor and a good step ahead of any other current smartphone. Noise is very well controlled as well. At 5x a loss of detail and texture becomes more obvious but the images are still usable at smaller output sizes, for example in social media.

5x zoom

The 10x zoom image shows the typical softness and pixelation we are used to from digital zoom images and is best reserved for emergency situations. That said, while the P20 Pro’s zoom can’t compare to the optical zoom of a compact camera, it’s outstanding for a smartphone camera. Kudos to Huawei for squeezing the technology into the thin body of a mobile device.

10x zoom

The zoom is still usable in indoor light conditions and produces results that, in terms of detail and noise, aren’t far off from images captured in bright outdoor light.

Wide angle 3x zoom
5x zoom 10x zoom

The Huawei’s zoom is not only handy for magnifying elements of the scene, just like the optical zoom on a “real” camera it also helps compress the planes of a scene. In the wide-angle image below the mountain range in the background is so small, it’s hardly noticeable.

In the 3x zoom image the mountains have become a much more important element of the composition, thanks to compression. However, in the zoom image the color response is much less vibrant and the camera tends to be a little more prone to highlight clipping. Hopefully that is something that can be fine-tuned for the final software version.

Wide-angle
3x zoom

While zoom performance is generally pretty amazing for a smartphone camera, we found exposure to be very unstable when zoomed in. Once zoom is activated you can get very noticeable exposure jumps between two images in a series, as you can see in the 3x zoom samples below.

We would expect this bug to be fixed with a software update, hopefully for the final release of the production software.

Underexposure Slight overexposure

Portrait/Aperture modes

Like most current high-end phones, the P20 Pro offers a background-blurring Portrait mode. The feature works very well with head-and-shoulder type portraits. The default blur strength is pleasant and the masking of the subject is quite accurate. Only some minor segmentation artifacts are visible in the hair of the subject below.

Portrait mode

Things don’t look as good with full-body portraits, however. Like in the shot below, on most occasions Portrait mode does not trigger for this type of scene.

Portrait mode

Portrait mode applies a degree of skin tone smoothing to your subject’s face. If you don’t want that, or take an image of an object rather than a person, you can switch to Aperture mode which artificially blurs the background in the same way as Portrait mode.

As you’d expect, the mode delivers similar results as Portrait mode but more complex objects, such as the bicycle in the image below, can cause some trouble, especially when shooting zoomed in. Foreground/background separation in this shot is pretty bad, with a lot of blur applied to areas that should be sharp and vice versa.

Aperture mode, 3x zoom

Video

Video, and particularly video image stabilization, are strong points of the Huawei P20 Pro camera. The clip below was shot hand-held and is very stable and smooth, almost steady-cam-like. No judder, over-compensation or similar kind of artifacts are visible. Other than that, detail is in line with the competition and the color response is similar to still image mode.

Conclusion

We’ve only had a few days with the Huawei P20 Pro but that has been long enough to say it is the most advanced smartphone camera to date. General image quality is very good, with good detail, very low noise levels across all light levels and excellent dynamic range. In terms of those parameters the differences to other flagship smartphones, for example the Google Pixel 2 or Samsung Galaxy S9 Plus aren’t massive, however.

Where the P20 Pro really leaves the competition behind is zoom. The dedicated 3x tele-lens provides a real advantage in the zoom department and makes this device the best current smartphone for zooming. The triple camera is also capable of creating a natural looking bokeh simulation, and in video mode the image stabilization is up with the very best, creating an almost steady-cam like effect.

There are still a few niggles in the camera software but hopefully those will be ironed out for the final release and our full review. It’s still early in 2018, but it’ll be interesting to see what the competition will come up with later in the year in order to counter Huawei’s impressive move.

Behind the scenes: Shooting Lamborghinis in the snow

16 Mar

Every year, Lamborghini puts on something called the “Winter Accademia.” It’s a week-long event wherein professional racing drivers teach clients how to drive the latest Lamborghini supercars on snow and ice—in short: one of the coolest events a motorsport photographer could cover. And this year, motorsport photojournalist Jamey Price was there to document the whole thing.

I stumbled across Jamey’s story earlier this week on Facebook, where he shared the Behind the Scenes video above. But rather than just post the video without further context, I reached out and asked Jamey for some details about the Winter Accademia and what it’s like to shoot it.

What he ended up sending us is worth publishing in full, so read on to find out what it’s like to shoot the Lamborghini Winter Accademia 2018, and then scroll through the gallery at the bottom to see some Jamey’s favorite shots from the event.


Shooting the Lamborghini Winter Accademia 2018

Every winter, Lamborghini North America organizes a driving event called Winter Accademia for existing and prospective clients to drive the latest Lamborghini models on snow and ice. Most people see a Lamborghini as an exotic car meant for driving in “normal” conditions, but in reality, with a little help from Pirelli winter tires with small metal studs, they are more than capable as performance cars on the ice too.

I’ve been fortunate to work with Lamborghini since 2013 covering races, as well as private driving events, concours and auto shows around the United States. This is simply one of the many events that is organized for the brand during the year. But as you can guess, it’s one of my favorites.

Lamborghini descended on Hotel Sacacombie on the lake that bears the same name in Quebec for a week of driving in late February and early March. The cold temperatures during the winter freeze the lake with over 30 inches of ice, which is more than enough to drive on. The track is simply a plowed section of snow on the frozen surface of the lake where we can run a drift circle, figure eights and the full track where a team of 7 professional racing drivers can teach clients the finer points of drifting a Lamborghini.

As a photographer, it doesn’t get much better than this. Yeah, it’s long days in the cold which is brutal on both the gear and myself, but it’s amazing photography chasing these high performance cars in an environment that is very contained, safe and, most of all, fun.

Especially with the professional drivers, I can put myself in places I would never consider standing under normal conditions at a track. Because everything happens in slow motion on the ice, you can get pretty close and capture lots of photos of the cars completely sideways and throwing snow and ice into the sky.

Google explains the tech behind the Pixel 2’s Motion Photos feature

15 Mar

Apple was the first mobile manufacturer to popularize still/video hybrid files with its Live Photos that were introduced on the iPhone 6s. Google then launched the Motion Stills app to improve and stabilize Apple’s Live Photos, and ported the system to the Android world soon after.

For the new Motion Photos feature on its latest Pixel 2 devices Google built on Motion Stills, improving the technology by using advanced stabilization that combines the devices’ soft and hardware capabilities. As before, Motion Photos captures a full-res JPEG with an embedded 3 second video clip every time you hit the shutter.

However, on the Pixel 2, the video clip also contains motion metadata that is derived from the gyroscope and optical image stabilization sensors.

This data is used to optimize trimming and stabilization of the motion photo and, combined with software based visual tracking, the new approach approach aligns the background more precisely than we’ve seen in the previous Motion Stills system (which was purely software-based). As before, the final results can be shared with friends or on the web as video files or GIFs.

If you are interested in more technical details of the Motion Photos feature, head over to the Google Research Blog. A gallery of Motion Photo files is available here.

Google just made the tech behind its ‘portrait mode’ open source

14 Mar

Semantic image segmentation is the task of categorizing every pixel in an image and assigning it a semantic label, such as “road”, “sky”, “person” or “dog”. And now, Google has released its latest image segmentation model as open source, making it available to any developers whose apps could benefit from the technology.

The function can be used in many ways. One recent application in the world of smartphones is the portrait mode on Google’s latest Pixel 2 devices. Here, semantic image segmentation is used to help separate objects in the foreground from the image background. However, you could also imagine applications for optimizing auto exposure or color settings.

This kind of pixel-precise labeling requires a higher localization accuracy than other object recognition technologies, but can also deliver higher-quality results. The good news is that Google has now released its latest image segmentation model, DeepLab-v3+, as open source, making it available to any developers who might want to bake it into their own applications.

Modern semantic image segmentation systems built on top of convolutional neural networks (CNNs) have reached accuracy levels that were hard to imagine even five years ago, thanks to advances in methods, hardware, and datasets. We hope that publicly sharing our system with the community will make it easier for other groups in academia and industry to reproduce and further improve upon state-of-art systems, train models on new datasets, and envision new applications for this technology.

If you are interested in finding out more about DeepLab-v3+, head over to the Google Research Blog for more details.
