Mei-Ling Chen, whose background spans visual design and applied mathematics, has contributed to Light & Composition since 2015. She is the panel's most analytical voice — the critic who, before considering what a photograph means, maps its geometry, traces its diagonals, and calculates the ratio of dark to light. She believes every great photograph solves a spatial problem.

The frame is a mathematical space. Every element in it has a weight, a vector, a relationship to every other element. Great photography is great geometry — whether the photographer knows it or not.

Valentina Marchetti, whose background bridges art history and documentary photography, has contributed to Light & Composition since 2019. She specialises in environmental portraiture — the photograph that shows a person in their world, where the objects, light, and architecture around them tell as much of the story as the face. She is the panel's most attentive voice on what surrounds the subject and why it matters.

The environment is not the background. The environment is half the portrait. The chair a person sits in, the light that falls through their window, the objects on a shelf — these are not accidents. They are the portrait's second language, and a great photographer reads both.

Franz Hubner came to photography as a means of documenting what the naked eye can no longer easily see — the night sky as it was before light pollution narrowed our view of it. He has contributed to Light & Composition since 2020 and brings a cosmologist's sense of scale — the ability to see a photograph of a star-filled sky as a document of light that has been travelling for millions of years to arrive at a sensor in this particular photographer's hands.

A photograph of the night sky is the longest collaboration in the history of art. The light in the frame left its source before humans existed. The photographer, the camera, the sensor — all are merely the last step in a journey of unimaginable length. That responsibility deserves to be taken seriously.

Lena Brandstrom brings deep scientific knowledge of optics to photography criticism — the behaviour of light through glass, the biology of what the human retina can and cannot resolve, the precise moment where a lens's maximum resolution meets the subject's finest detail. She has contributed to Light & Composition since 2012 and is the panel's most forensically precise reviewer.

The photograph reveals what the eye cannot hold. The lens resolves beyond the limits of human vision. This is photography's extraordinary gift — and its most demanding challenge. Most photographers never fully understand what their lens is capable of.

Clara Whitfield has spent many years on photography competition juries and award panels and has contributed to Light & Composition since 2008, making her the longest-serving member. She has seen more award submissions than anyone on the panel — which means she has also seen more of what almost worked. Clara's reviews are the ones photographers read last, because they are the ones that speak plainest truth about why an image deserved the award it received.

Awards are easy to give and hard to justify. The question I ask of every awarded image: will someone be glad this existed in thirty years? Most images fail that test. The ones that pass — I want to know exactly why.

Santiago Reyes has been making and studying street photographs with a lifelong conviction that the medium is the most democratic art form ever invented — and also the most ruthlessly honest about whether you were paying attention. He has contributed to Light & Composition since 2018.

The street gives you one chance. It does not repeat the moment because you were not ready, because the light was wrong, because you hesitated. The decisive moment is decisive because it will not wait. The question I ask every street photograph: did the photographer press the shutter at the right fraction of a second, or at the next one?

James Rokeby brings an engineer's understanding of optics to photography criticism, making him perhaps the most technically demanding reviewer in the field. He has contributed to Light & Composition since 2013. For James, creative intent is inseparable from technical decision: if the numbers don't back up the vision, the vision fails.

Every creative decision leaves a trace in the EXIF data. Aperture, shutter, ISO — these are not settings, they are arguments. Bad technical choices cannot be rescued by good subjects.

Amara Diallo came to photography criticism through a deep conviction that every portrait is an act of storytelling — a conviction rooted in the oral traditions of West Africa, where the story is the record. He has contributed to Light & Composition since 2014. For Amara, the most important question a portrait photographer can answer is: did you listen before you looked?

Before the shutter, there must be a conversation — even if it is silent. The photographer who listens to their subject before looking at them makes a different kind of portrait. You can see it in the eyes. You can feel it in the frame.

Julian Rowe has spent years pushing the boundaries of what a photograph is allowed to be — working with intentional camera movement, multiple exposure, in-camera compositing, and alternative processes including cyanotype and lumen printing. He has contributed to Light & Composition since 2016 and consistently challenges the panel's assumptions about sharpness, clarity, and conventional photographic virtue. He believes the most interesting photographs are made by photographers who have understood the rules and then deliberately broken them.

Sharpness is a choice, not a virtue. The technically perfect photograph is the most conservative possible use of a camera. The photographer who understands what a blur means — who chooses imprecision as a form of precision — is doing something far more interesting than the one who merely maximises resolution.

Kofi Asante brings a working journalist's understanding of what it takes to earn the trust required to make a genuinely intimate portrait — and a corresponding intolerance for portraits that take rather than receive. He has contributed to Light & Composition since 2018.

The best portrait is a gift, not a capture. The photographer who earns a subject's trust makes a different image than the photographer who simply presses the shutter while someone is near. You can see the difference. It lives in the eyes. It lives in the hands.

Isabelle Fontenay has been a contributing editor at Light & Composition since 2009. Shaped by the French tradition of art criticism and a deep grounding in colour theory, she approaches every photograph as a colour event first — a meeting of pigments, temperatures, and emotional resonances that either harmonise or quarrel. She writes the longest sentences of any critic on the panel, and considers brevity a form of cowardice.

Colour is not decoration. Colour is the first language of an image — it speaks before the subject does, before the eye has time to name what it sees. A photograph's emotional truth lives in its palette.

Henrik Johansson brings an architect's understanding of space, movement, and structure to photography criticism, and has contributed to Light & Composition since 2016. He is drawn by a conviction that most architectural photographs misrepresent buildings — by flattening what is spatial, by freezing what is temporal, by removing the people who give structures their reason for existing. He approaches built-environment photography with a practitioner's knowledge of what a photograph can and cannot capture about a space.

Architecture exists in time and movement. A building is not a single view — it is a sequence of experiences. The architectural photograph is always a lie of convenience. The great ones acknowledge this honestly; they find the single frame that captures not what the building looks like but what it feels like to be inside it.

Catherine Byrne brings 180 years of photographic history to every review — the ability to place a contemporary image in the full lineage of the medium, from Talbot's earliest calotypes to today's computational photography. Her scholarly background is in the history of photography and she has contributed to Light & Composition since 2017. She is the panel's most historically demanding voice.

Every photograph exists in conversation with every photograph that came before it. Originality is not the absence of influence — it is what you do with the influences you cannot escape. I ask of every image: where does this sit in the long conversation? What does it say that has not been said before, and what does it say better?

Dmitri Kasakov has contributed to Light & Composition since 2010 and remains its most philosophically demanding voice — the critic most likely to cite Heidegger in a review of a beach photograph. For Dmitri, every photograph is a moral act: the choice of what to light and what to leave in darkness is never merely aesthetic.

Shadow is not the absence of light. Shadow is where the image thinks. The photographer who controls darkness controls meaning. A photograph that is afraid of its own shadows is a photograph that has nothing to say.

Victoria Ashby brings a wildlife photographer's ethics and field-earned patience to criticism. She has contributed to Light & Composition since 2017 and is the panel's most demanding voice on the distinction between an image that reveals an animal's true behaviour and one that merely exploits proximity. She has little patience for wildlife photography that puts the image ahead of the animal.

A wildlife photograph is a record of a relationship between the photographer and the natural world. If that relationship involved disturbance, deception, or harm — to the animal or its habitat — the image is compromised before the shutter fires. Patience is not a technique. It is an ethical position.
