The invisible city is not underground, exactly. It is the city that operates alongside the visible one — using the same streets, the same transit, the same parks — but under different terms. It is the city of people who work in the hours that other people sleep, who occupy public space in ways that urban design did not anticipate, who have organised communities around needs that official institutions do not acknowledge and official maps do not show.

The project began with a single image: a night cleaner photographed at 4am in the Vienna U-Bahn, sitting in a circle of colleagues in the interval between trains, eating dinner from a shared pot. The meal was elaborate — clearly made with time and care — and the space it occupied was absolutely temporary. In forty minutes, the trains would start again. I had stumbled into a community that had made a home in the gap between other people's days.

The Methodology

Three years, six cities, four languages, and a translator in each. The access required was built slowly — through sustained presence, through returning without a camera first, through the kind of patience that photojournalism rarely allows and documentary work must insist upon. The photographs that resulted are not candid in the conventional sense. They are made portraits: images where the subject understood what was being asked and chose to participate. The dignity in them is not imposed. It was present already.

What the Cities Hide

European capitals present themselves as administered, legible, and fully mapped. The bureaucratic systems that manage them are among the most sophisticated ever developed. And yet: the informal economy that keeps them running, the communities that live in administrative gaps, the labour that is visible only in its absence when it goes wrong — none of this appears on the official map. Photography cannot correct this. It can make it harder to not see.

Common Questions

Slowly, and without the camera at first. Trust is built through presence, consistency, and genuine interest in the community on its own terms rather than as a subject to be photographed. The camera is introduced only when the relationship can bear it.
Candid photography records subjects without their knowledge. Documentary photography at its best is collaborative — the subject understands the purpose and chooses participation. The ethical distinction matters both for the subjects and for the integrity of the work.
The key is specificity over generality. A dignified image is specific — it shows this person in this moment, with the full complexity of their particular situation. Aestheticised poverty tends toward the generic and the symbolic, collapsing individual specificity into visual shorthand.
