Flame plasma pyrolysis process turns spent coffee grounds into biofuel

Gizmag news -

Humans drink approximately 400 billion cups of coffee annually, leaving behind 18 million tonnes of wet coffee grounds, roughly the weight of the three Great Pyramids of Giza. These grounds, which mostly end up in landfill, have the potential to be fuel. However, their moisture poses a significant challenge. Scientists at the Korea Institute of Geoscience and Mineral Resources (KIGAM) have devised a technique to turn still-wet coffee grounds into high-grade biofuel in as little as 90 seconds.

Article of the month: Joining a local photography group

"A group shot (excluding me) of that first meetup that I attended."

Photo: Abby Ferguson

DPReview's Features Editor, Abby Ferguson, wrote a great piece about the benefits of joining local photography groups. As a community manager, I naturally found this article fascinating and the kind of advice I feel all of you would find a great insight into photographers outside our forums. After reading her article, I even took it upon myself to look up some photography groups in my local corner of Texas, United States.

"Despite my reluctance, I knew meeting other photographers would only be a good thing. Plus, as this is a place my husband and I will be for the long term, I wanted to set down some roots and finally make some connections here. And so, last fall, I finally put aside my reservations and attended a meetup." - Abby

What's in your bag? A community member spotlight

Every week, we spotlight a community member's unique photographs and gear in our 'What's in your bag?' series. The series highlights a reader's favorite camera gear and how they use it. You'll also get tips and tricks on capturing your own photography.

Mark Lamb shared his portrait photography in celebration of our week of portrait-themed community content. Below is an interesting excerpt from Mark's story about his fondness for portrait photography in Britain. The photo above is a new one he provided us that we couldn't fit into the article.

"In recent years, my work has become centered on a long-term project called One Thousand Contemporary Portraits, an attempt to create a broad and inclusive portrait archive of contemporary Britain. The project has taken me from fishing communities and military veterans to Goths, performers, campaigners, artists and ordinary people whose stories might otherwise go unrecorded."

Question of the week: we ask, you tell

Every other week, we ask the community a question about their photography, usually on a specific topic, with the results spotlighted on DPReview's front page and in the forums the following week. There are often many great photos submitted that we don't get a chance to spotlight them all in a single article.

Here is a newly revealed reader's photo and excerpt of their story from the latest question.

What camera is your most memorable? Photo: thorstenwulff

Featured quote: "My first love was the F3. In the summer of 1987, she went to New York with me and a box of T-Max 400. Paired with a 24mm F2.8 lens, it was my perfect combo for street photography, even if you had to get a bit closer. The other lens was the 105mm F2.5. In early May this year, I took them back to Manhattan, but was put off a bit by the flood of gimbal-toting influencers everywhere Instagram deems worthy of a shot. This couple is one of my favorite pictures from 39 years ago. I love the tenderness between them." - thorstenwulff

Every week, new community-created photo discussions and mini-challenges pop up across the forums. Usually, these start as a discussion about a particular camera brand or type of photography. For the month of June, we wanted to highlight Alan WF's invitation to take fresh photos with your adapted lens cameras.

Visit our Community photo threads index for the latest opportunities to share a photo from your collection. We would also love for you to participate in DPReview's own initiatives: Weekly photo exhibitions and the new Collaborative photo chain.

Discussion of the month: Why is it so difficult to buy a first camera today? Photo: FrancoD

Community member, BernardoSC, asked a great question in the forums that has gained quite a bit of traction. He asked everyone, "Why is it so difficult to buy a first camera today?" This is an excellent question, BernardoSC! I have asked this question of myself recently about various purchase interests, from cameras to computer equipment.

Here is a peek at what others had to say:

JT26: It's hard as there are so many options now. New cameras and new versions of the above are using new tech and are not sold in millions like they used to be, so they are naturally more expensive.

ahaslett: The optical viewfinder is what limits your choice. Apart from retro designs, cameras these days are nearly all mirrorless. There isn’t much between a phone and a camera for £1,000, given how fast phones have improved.

Plankowner110: In the 1960s, you simply adjusted aperture, shutter speed, and focus ring, and it didn't matter if you were using an inexpensive Sears Tower (camera) or a rugged pro-body Nikon F. The major variable was selecting which film to use. Cameras all operated basically the same way, and one could easily pick up any brand of camera and begin shooting. We didn't have to peruse a myriad of menu settings or press tiny re-programmable buttons all over the camera body.

From coral reefs to abandoned theaters: meet the 2026 Hasselblad Masters

Digital Photography Review news -

Hasselblad Masters 2026 winners Photo: Kevin Boyle

Hasselblad has announced the winners of the Hasselblad Masters 2026 photography competition. The contest awarded 7 photographers from 70 finalists, chosen from more than 108,000 submissions across 160 countries.

Winners were selected across seven categories: Landscape, Architecture, Portrait, Art, Street, Wildlife, and Project//21. The winning photographers were selected by the Hasselblad Masters Grand Jury, which included representatives from National Geographic, Magnum Photos, Aperture Magazine, Getty Images, Foam, The Metropolitan Museum of Art and the Three Shadows Photography Art Centre. Images were chosen based on their conceptual strength, originality, creativity and technical excellence.

The competition drew some attention earlier this year when Hasselblad confirmed it had disqualified one shortlisted photographer for including AI-generated elements in violation of competition rules, replacing them with a new finalist. It's worth noting that the finalists were selected through an internal selection process at Hasselblad, not by the acclaimed photographers on the Grand Jury. A representative has confirmed that all of the winning images were "thoroughly vetted, and EXIF data was confirmed," and that they are all authentic photographs.

Each winner receives the title of Hasselblad Master, a Hasselblad medium format camera, two XCD lenses, and a €5,000 creative fund. Their work will also be featured in the commemorative Hasselblad Masters book.

We're showing one image per winner below, but you can view all three selected images for each photographer on the Hasselblad Masters website. Traditional captions and EXIF data were not available, and the descriptions and jury quotes accompanying each image are taken directly from Hasselblad's competition materials.

Art winner: Yudha Kusuma Putera

Yudha Kusuma Putera | Waste Colonialism (Sapi-Sapi Piyungan) | Indonesia

Rooted in everyday life and inspired by its complexity, Yudha Kusuma Putera turns a keen eye toward the social issues that hide in plain sight, exploring the tensions between humans, nature, and the systems we build around us.

The winning images are part of a project examining how developed nations export their waste to developing countries, where labor and costs are lower. This logic repeats on a smaller scale too: within cities, landfills are built on the outskirts, kept out of sight and out of mind. At Yogyakarta's Piyungan landfill, a city's waste is sorted by scavengers and consumed by cows, quietly piling up into a second hill.

'He photographed the backs of these cows stacked together, with their forms mirroring the landscape of trash around them. The work does not seek to assign blame, but to invite collective reflection on the waste we produce, and the futures we are building from it.

"On the surface, the images appear direct and unambiguous, and yet they consistently resist easy reading, generating a sense of visual uncertainty that keeps the viewer engaged and questioning. The images do not announce themselves loudly, but reward sustained attention with a slow-building sense of strangeness that is both intellectually stimulating and visually striking," says Kalle Sanner, Executive Director at the Hasselblad Foundation.

Architecture winner: Kevin Boyle

Kevin Boyle | DaySleeper | Movieland | Canada

Kevin Boyle was shaped by the open skies and close-knit communities of the Canadian prairies. After the loss of his father, he returned home, only to find the places he once knew hollowed out and silent, their gathering spaces boarded up and left to disappear. For over ten years, his photographic journey has been a profound tribute to the abandoned architecture of North America's local communities.

The winning series is comprised of photographic montages, with each part of the building lit with flashlights and blended in post-production to create an ethereal 'portrait' of once important gathering places. Through his lens, these forgotten spaces become vibrant, glowing symbols of community heritage and shared human connection.

"The composition, and the fact that the images are empty of people, triggers our imaginations, taking us back to a time when these buildings would have thrived with the community meeting for evening entertainment. By making this series, the photographer invites us to consider the myriad of small venues that make up the social fabric of small communities," says Sonia Jeunet, Photography Consultant and Education at Magnum Photos.

Portrait winner: Svetlana Jovanovic

Svetlana Jovanovic | Otherness | The Netherlands

With a psychology background, Svetlana Jovanovic's portraiture is driven by a deep curiosity about identity – how we experience the world, construct our sense of self, and see ourselves through the eyes of others. Her style brings together fine art portraiture and a commitment to visual beauty, believing that the conceptual and the aesthetic are inseparable: each gives the other meaning.

The winning images are part of Otherness, an ongoing long-term project exploring identical twins and the tension between shared identity and individual presence. While twins share so much, it is the small differences that emerge over time, the subtle ways each person's character becomes visible within the shared image, that lie at the heart of the work. Each portrait is a collaboration, shaped as much by the relationship between the twins as by the photographer's own vision, inviting viewers to reflect on how we define ourselves both apart from, and through, one another.

"Through precise use of light and composition, this portrait series explores the themes of mirroring and duality. Whether capturing two sides of the same face or the closeness of two kindred souls, the images reveal subtle layers of emotion with quiet precision," says RongRong, Co-founder and Artistic Director at The Three Shadows Photography Art Center.

Landscape winner: Rohan Reilly

Rohan Reilly | Ephemeral Visions | Ireland

Rooted in the discipline of a composer, Rohan Reilly's images strip away complexity to reveal the essentials, which are texture, tone, and stillness. His signature long-exposure technique transforms moving water and shifting skies into silk-like surfaces, while vast negative space and low saturation give his work a poetic, meditative quality that transcends documentation. The process is one of patience and preparation: studying weather patterns, returning season after season, and waiting for the precise conditions that cannot be engineered but only earned.

This winning series captures a row of poplar trees planted along the banks of the River Po in Italy, which are natural guardians against flooding, now standing immersed in perfectly still water beneath soft, diffused light. What was once a purely functional landscape transforms into something surreal and dreamlike. In this quietly breathtaking scene, the photographer's vision can find its fullest expression: nature distilled to its core, and time momentarily held still.

"A forest of birch trees could be a monotonous subject. But these photographs are hypnotic objects of meditation, creating something expansive through repetition and ostensible sameness," says Zack Hatfield, Managing Editor at Aperture Magazine.

Project//21 winner: Panitbhand Paribatra Na Ayudhya

Panitbhand Paribatra Na Ayudhya | Dwellers of the Night | Thailand

Panitbhand Paribatra Na Ayudhya is a young underwater photographer and scuba diver from Thailand. His work is rooted in a quiet dedication to the ocean, documenting its life, its fragility, and the ecosystems that sustain it, in the hope that what is seen through his lens will not be forgotten.

His winning series was captured in the waters of Anilao, Philippines, where pelagic and larval marine life migrate from the depths each night to feed under the cover of darkness. Using slow shutter speeds to capture the elegant motion of his subjects, and carefully chosen coloured lighting to reveal their form and beauty, he illuminates a world rarely seen. For the ribbon eel, a diffused warm light conjures a subtle sunset behind the subject – crowning it as a master of the night. Some of these creatures spend their entire lives in the open ocean, making the pelagic ecosystem as fragile as it is extraordinary.

"I'm drawn to the quiet whimsy of these sea creatures. Set against black, the creatures feel almost otherworldly- strange, delicate, and entirely captivating. There’s a simplicity to the presentation that allows their inherent oddness to shine, reminding us how unfamiliar and compelling the natural world can be when seen without distraction," says Alex Pollack, Director of Photography at National Geographic.'

Street winner: Gosse Bouma

Gosse Bouma | Morning Ritual | The Netherlands

Gosse Bouma is a photographer whose work is driven by a quiet pursuit: to offer moments of tranquility in a world that rarely slows down. His distinct style lies at the intersection of urban geometry and natural elements, pairing the hard lines of architecture with the soft, unpredictable textures of weather. Each photograph is infused with the intention of invoking serenity amidst the chaos of everyday life, creating visual experiences that invite stillness and reflection, even if only for a fleeting moment.

His winning series, taken across the Netherlands, turns to the street market as its subject, a space where people of all ages and backgrounds meet, exchange a few words, share warmth, and move on. In capturing these small, unhurried encounters, Bouma preserves something increasingly rare in contemporary life: a genuine sense of togetherness.

"The photographer understands atmosphere, scale and timing. The small lit kiosks within the vast blue urban emptiness create images that feel both intimate and monumental. Here, genuine photographic tension emerges. The series uses color structurally, not decoratively. Mist, artificial light and architecture form one coherent world," says Aya Musa, Senior Curator at Foam.

Wildlife winner: Alfred Minnaar

Alfred Minnaar | The Forest I Roam | South Africa

Alfred Minnaar's creative process often begins with observation and patience. Rather than simply documenting his subjects, he seeks to understand their behavior, environment, and relationship with the surrounding ecosystem. Over a decade of global exploration, his fine-art philosophy has evolved from a traveler's passion into a powerful voice for conservation, capturing fleeting deep-sea and wildlife narratives to inspire the preservation of our planet.

The winning images of a tiny goby living amongst coral were created to challenge our perception of scale and encourage viewers to look closer. Rather than focusing solely on the fish, the photographer wanted to use it as a point of reference within a much larger world. By placing the goby within its environment, the reef itself becomes the subject, inviting viewers to imagine its vastness from the perspective of one of its smallest inhabitants.

"The vibrancy of the palette immediately draws you in, and the way the small fish are framed against their environments creates a sense of scale that almost reads as landscape. There’s a nice balance here between detail and composition, with the micro subjects holding their own within a larger, almost abstracted environment," says Alex Pollack, Director of Photography at National Geographic.

World's first narrow-gauge hydrogen train built for Italy's historic tracks

Gizmag news -

Swiss locomotive manufacturer Stadler and Sardinian regional operator ARST (Azienda Regionale Sarda Trasporti) have unveiled the world's first hydrogen-powered train built for narrow-gauge track. That's a genuine first because the narrower track imposes axle-load limits so tight that no existing hydrogen train could fit, and an entirely new vehicle had to be designed from scratch.
