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.

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?

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.

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.

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.

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.

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.

Yusuf Al-Hamdan brings a practitioner's reverence and deep patience to every review. He has contributed to Light & Composition since 2011, with a particular admiration for the photograph that required patience — the one that could not have been taken by anyone who was in a hurry.

Light is not something the photographer uses. Light is something the photographer listens to. The landscape photograph is an act of attention — the shutter is pressed not when the photographer decides, but when the land is ready.

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.

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.

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.

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.

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.

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.

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.
