NASA once rejected the sensor technology that is now in every smartphone camera

Digital Photography Review news -

CMOS sensors are now so ordinary that it's easy to forget how transformative they were. They're used in an ever-growing list of devices, from dedicated cameras, smartphones and webcams, to security systems, glasses and cars. A new video from the California Institute of Technology (Caltech) looks at how the CMOS image sensor, once a space-imaging technology tied to NASA and the Jet Propulsion Laboratory (JPL), became one of the defining inventions of the digital age.

The short video traces the sensor's path from deep-space imaging work intended to photograph Saturn up close to everyday devices. It highlights the roles of engineers Eric Fossum, the inventor of the modern CMOS sensor and a longtime friend of DPReview, and Sabrina Kemeny. It walks through the idea of the "camera on a chip," with a useful visual for understanding how it works and how it differs from CCD technology.

Interestingly, even though the team had success right away, NASA wasn't interested at first. "We were trying to get them to adopt this technology that we thought was the greatest thing since sliced bread, and they just weren't that interested," said Kemeny in the video. That's because the scientists didn't know how it would handle the harsh conditions in space, and they needed a camera that they could be confident would perform when spending millions on a mission.

That led the team to seek out industry applications, which snowballed into what we now see today. "I had no idea how massively useful or ubiquitous it would be," said Fossum. Of course, the CMOS sensor did eventually make its way back to NASA, with the Perseverance rover on Mars using the technology to send back photos and videos from the distant planet.

The video is part of a series that highlights how research moves from the laboratory to daily life. It's a good example of how scientific research can find its way into everyday tools, including those used by photographers. After all, the same broad push to make cameras smaller, more efficient and more capable helped set the stage for the image-saturated world we live in now.

This photographer documents Chornobyl with cameras he can never bring home

Digital Photography Review news -

Photo: Kamil Budzynski

Since 2018, Polish photographer Kamil Budzynski has been placing homemade pinhole cameras throughout the Chornobyl Exclusion Zone, leaving them in abandoned buildings, trees and other locations for months at a time. The resulting solargraphs are strange, quiet and even disorienting. Ghostly buildings and overgrown streets sit beneath bright arcs traced by the Sun, thanks to exposures that can stretch across seasons. Kosmo Foto recently published a fascinating interview with Budzynski about the long-running project.

Budzynski first visited the exclusion zone in the mid-2010s, but after several trips, he began looking for a process that could better match the feeling of the place. "After three trips to the Chornobyl exclusion zone, I began to feel that I couldn't do the place justice by walking around with a digital camera," he said. "Searching for inspiration in niche photographic processes, I came across solargraphy just as I was about to pack for another visit."

"I began to feel that I couldn't do the place justice by walking around with a digital camera"

For the unfamiliar, solargraphy is the process of capturing the Sun's path across the sky over long periods (days, weeks or even years) using pinhole cameras. Budzynski's cameras are often made from simple objects such as 35mm film canisters, drink cans and small tins, loaded with very low-sensitivity photographic paper and fitted with carefully made pinholes. He has installed more than 100 of them, though not all have survived because of Ukraine's harsh winters or Russia's invasion. After retrieving the exposed paper, Budzynski leaves the cameras behind to avoid bringing any radioactive particles out of the exclusion zone.

The distinctive look of the images is not the result of radiation, despite their months-long stay in the exclusion zone. Budzynski told Kosmo Foto that "for nuclear radiation to affect photosensitive paper it would need to be far too dangerous to get near it," but added that the weather was a much bigger challenge. Moisture, freezing temperatures and months of exposure can all leave their mark on the final image.

What makes the project more than a visual curiosity is how well the process matches the subject. Budzynski is using a camera to record time passing through places many people still think of as frozen in 1986. That distinction feels especially relevant this year, as April 26 marked 40 years since the Chornobyl nuclear disaster. Pripyat was evacuated the day after the accident, and tens of thousands of people were ultimately removed from the surrounding area. Budzynski's images push against the familiar "ghost town" shorthand by showing that the zone is not static.

"I wanted to capture the passing of time in a literal sense"

"I wanted to capture the passing of time in a literal sense," Budzynski told Kosmo Foto. "Pripyat and the entire exclusion zone may be frozen in 1986 to us, but life there continues. Stray dogs and wild horses roam the empty streets, plants climb tall buildings, and the sun still rises every morning – whether we are there to see it or not. I hope I can convey how insignificant I feel when standing among the ruins to those looking at my photographs."

Russia's 2022 invasion altered Budzynski's solargraphy trips. He has returned to Ukraine since then on humanitarian trips, during which he was able to recover a few cameras. "Most cameras from this period did not survive, destroyed by Ukrainian forces searching for booby traps and other surprises left by the retreating Russian army," he said. "I had quite a lot of explaining and apologizing to do when our guards learned of my little innocent photography project. One particular camera left right near the power plant caused quite a stir."

Kosmo Foto's full interview goes much deeper into Budzynski's process, the locations he has photographed and the practical problems of hiding a pinhole camera in a place where both weather and history are working against you. It is worth reading in full, both for the mesmerizing images and for the way the project's technical limitations become part of the story rather than obstacles to it.

Wild Sichuan: Photographing rare mountain species (China series: Part 2)

Digital Photography Review news -

Photo: Erez Marom

In the previous article about photographing mammals in China, I told the story of photographing black-and-white snub-nosed monkeys in Yunnan – the first of two species of snub-nosed monkeys I had the opportunity to capture. I'll tell you about the second species in the next article, but before we get to that, I'd like to tell you about a couple of pit stops I made to shoot other kinds of mammals.

The pit stop was mainly planned to make use of a day that would otherwise be dedicated to driving. Tangjiahe National Nature Reserve, a renowned 40,000-hectare biodiversity hotspot in Qingchuan County, Sichuan Province, was on my route and allowed me to spend more time shooting, even if it was a very short visit. Tangjiahe is recognized globally as a premier spot for wildlife viewing, and the landscapes on the way – and in the park – are breathtakingly beautiful.

Upon entering, I was greeted by a face only a mother could love: that of a very aggressive Tibetan macaque. The macaques are far from shy and are known to harass human visitors, meaning that one must approach them with caution. I got my fair share of aggressive grinning behavior and decided to retreat before getting into an actual fight with a monkey and ruining the rest of the trip.

I found it hard to make out this look by the Tibetan Macaque. One second, it was quiet; the next, it gave me the feeling that I was asking for trouble. In any case, I loved how colorful its face was.

Tangjiahe is home to a wide selection of mammal species. While not all of them are that exciting, I found a lot of pleasure in viewing and shooting things I don't usually take an interest in, specifically ungulates. I found a few muntjac (barking deer) gently grazing the mountain slopes.

Reeves's Muntjacs are roughly the size of a medium dog, featuring distinct facial markings, long canine tusks in males, and a tendency to be solitary, nocturnal herbivores.

A more visually-interesting animal was the Sichuan takin - a large, muscular mountain ungulate native to the eastern Himalayas and the mountainous forests of southwestern China, especially in Sichuan province. It has a distinctive appearance – often described as a cross between a goat and an ox – with a heavy body, thick coat, and a prominent, arched nose that helps warm cold mountain air before it reaches the lungs. Both males and females have strong, curved horns, and their dense fur, along with oily skin secretions, helps them withstand cold, wet alpine environments.

Takins have such distinct and interesting builds and features. I love the elongated face and short horns; it gives them a bit of a mythological appearance. Do you agree?

Sichuan takins live in herds that move seasonally, climbing to higher elevations in summer to graze on grasses, bamboo, and leaves, and descending to lower, forested areas in winter, which is the reason I could shoot them with relative ease. They are well adapted to steep, rugged terrain and can navigate cliffs with surprising agility despite their bulk. The species faces pressures from habitat loss and historical hunting, but it is protected in China, with populations found in reserves, such as Tangjiahe, that also shelter the giant panda, making conservation efforts for both species interconnected.

I tried to get a shot of a takin crossing the stream, but at the last second it backed off.

Another location I'd like to talk about is Wawu Mountain (Wawushan), a striking flat-topped massif in Sichuan Province, rising like a vast natural plateau above surrounding valleys. Known for its sheer cliffs, dense temperate forests, and frequent cloud cover, it creates a dramatic, almost otherworldly landscape. Wawu's table mountain topography supports a rich mosaic of ecosystems, making it an important biodiversity hotspot.

Among its most charismatic inhabitants is the red panda, a shy, tree-dwelling mammal that thrives in Wawu Mountain’s cool, bamboo-rich forests. These elusive animals spend much of their time in the canopy, feeding on bamboo leaves, as well as fruits, insects, and small vertebrates. Wawu Mountain’s protected status and relatively intact habitat make it one of the better places to support completely wild red panda populations, and sightings are practically guaranteed if you spend 2-3 full days. The same ecosystem also shelters other notable species, linking Wawu’s conservation importance to the broader network of Sichuan reserves that protect iconic wildlife, such as the giant panda.

On the last morning, we even got some snow to accentuate the red pandas' beautiful red coloring.

Tiny bike camper expands via slide-out to sleep 2 people + toilet

Gizmag news -

Most bicycle campers just tow, but there are some that flip, that drop, that pitch and that straight blow up. The new Alpencamper adds another motion to that mix: sliding. The two-wheel towable borrows a trick from larger caravans and motorhomes, using a sidewall slide-out to expand its tiny interior enough to house a double bed comparable to what you'd find in a full-blown camper van – not bad for a little 'drop trailer that weighs less than the average adult.
