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.

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.

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.

Rafael Ortega approaches the single frame with the same rigour he gives to a sequence, and brings a filmmaker's obsession with time, rhythm, and the weight of a single held image to every review. He has been reviewing for Light & Composition since 2014.

A great photograph is a film that refused to move. Everything you need is in that one frame — the before, the after, the cut that never came. The question is whether the photographer understood what they were holding when the shutter closed.

Eleanor Voss has contributed to Light & Composition since 2011. A committed formalist, she believes that a photograph's enduring power lies almost entirely in the rigour of its visual architecture — the placement of mass, the tension of negative space, the discipline of the frame. She has little patience for sentiment without structure.

A photograph earns its place through formal rigour alone. Emotion without structure is noise. The frame either holds or it doesn't.

Priya Sharma, whose thinking is grounded in East Asian aesthetics and Japanese visual philosophy, has contributed to Light & Composition since 2012. Her criticism draws on the Japanese concept of Ma — the meaningful pause, the productive emptiness — and she is perhaps the only critic on the panel who considers what a photograph leaves out to be as important as what it includes.

Restraint is the hardest discipline in photography. Anyone can fill a frame. The photographer who can empty one — who can trust the silence — is rare. Ma: the pause that holds more than words.

Deepa Krishnan brings both a scientist's knowledge of marine ecosystems and a technical understanding of the profound optical challenges of underwater photography — the light absorption, colour shift, and backscatter that make every good underwater image a minor technical triumph. She has contributed to Light & Composition since 2019.

The underwater world follows different physical laws. Light is stolen by water — red disappears at five metres, orange by ten, yellow by twenty. The underwater photographer is working in a world that actively removes colour. Every image that has warmth and clarity below the surface has fought for it. I respect that fight, and I can tell when the photographer understands the physics of what they are doing.

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.

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.

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.

Marcus Trent brings a photojournalist's intolerance for artifice and his deep conviction that every worthwhile photograph is ultimately about a human being — either because a human being is in it, or because a human being felt something extraordinary in the moment they pressed the shutter. He has been reviewing for Light & Composition since 2015.

Photography is a human act before it is an aesthetic one. The question I ask every image: did the person behind the camera feel something true? If they did, the camera finds a way to carry it.

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.

Sophie Delacroix approaches photography criticism through the lens of perceptual psychology. She has been with Light & Composition since 2013. Her criticism focuses not on what is in the image but on what the image does — the sequence of emotional and cognitive responses it triggers in a viewer who has never seen it before and the one who returns to it a year later.

The photograph is not the thing in the frame. The photograph is what happens in the body of the person looking at it. A great image alters the viewer's physiology — pulse, breath, the specific sadness of a certain blue.

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.

Thomas Hargreaves brings a landscape practitioner's uncompromising standards to photography criticism. He has contributed to Light & Composition since 2010 and is the panel's most demanding voice on the subject of craft — specifically the craft of waiting, of returning to the same place in different weather, of earning the photograph rather than finding it. His dry wit has made him the panel's most quoted critic and occasionally its most feared.

The best photographs are expensive. They cost the photographer time, patience, and physical discomfort. I can usually tell from the image whether someone paid full price.
