HIDDEN – The fascination of hidden features, revealed by photography

6 min read

At first glance, all is pink. Like a doll’s house, carefree and relaxed. Except for a small, metallic structure in one corner. The toilet bowl amidst the pink clouds reveals the actual purpose: a cell. A prison. Hidden here is the rage, the outburst, the act of violence that may have led to this place.


Two glances further: wrinkled clods of earth on metal trays. An abandoned storeroom? Who could really have any use for such drab objects? The whole of Europe, in fact! The mushroom substrate of the premium mushroom culture in Kerns, Switzerland, is highly sought-after, since it comes from the only company to have successfully established a fully automatic production – and that in organic produce quality.

Hidden stories within fascinating, strikingly detailed pictures. 25 places that hardly anyone has been allowed to throw a glance at so far. The art project “HIDDEN” by the curator Catherine Iselin and the photographer Kostas Maros has made these places accessible without taking away any of their magic, touching and sometimes disquieting attributes. A view of Switzerland which goes effortlessly beyond national borders thanks to its complexity and great thematic diversity.

“Kostas Maros and I met each other 15 years ago at the University of Basel and soon found out that we were fascinated by similar topics. The invisible, the weird and the forbidden. We found ourselves in these again and again”, explains curator Catherine Iselin. With “HIDDEN”, their common interests have been combined in a joint project.

Numerous positive answers

“At a very early stage, we asked ourselves: What is the actual meaning of hidden? We then jointly developed the decisive criteria for selecting suitable places.” Over two years, they both collected ideas, researched and asked for admission again and again – and with success. “We were overwhelmed by the number of people who said ‘yes’”, the curator tells. Their obvious enthusiasm for their project and their intelligent, sensitive approach to portraying must doubtless have played a major part here.

„We did not intend to hand out anything on a silver platter.“
Catherine Iselin

One of the most important questions at the beginning of the project was the choice of a medium. “For me, the only suitable medium was photography – due to its character of authenticity. Had the hidden places been drawn or painted, the pictures would not have had the same effect”, Iselin emphasizes. Photography is seen as a form of documentation. It presents plausible images which inspire confidence in the viewer – an important prerequisite for recording hidden things. The project also deliberately works without text; it is not a report. “We did not intend to hand out anything on a silver platter. By doing so, all viewers can experience that fascinating, intimate moment of discovering something previously hidden to them.”

Structure and perspective

“HIDDEN” transcends the abilities of the human eye. Angles and details of the photos are larger and more varied than can be taken in at a single glance. This level of detail, however, is not inconsistent with what is hidden, since hidden things are often only materialised through precise observation and the pursuit of detail. This depends primarily on the perspective and professional expertise of the photographer. “Architecture and aesthetics are inseparable from the work of Kostas Maros. Whoever looks at his works can see how intensely he works with structure, ornaments and perspective.” Certainly one reason why he won the renowned Swiss Photo Award 2018 in the category of architecture with eight pictures from the series.

„The people who live and work there belong to this place; they complete the story.“
Catherine Iselin

From the beginning, Iselin and Maros were in agreement that the rooms should be photographed without people. “But once on site, we quickly realised that people and rooms are ultimately inseparable. The people who live and work there belong to this place; they complete the story. So we also took portraits of the people as an additional project”, says Iselin. Every person was photographed in front of a neutral background together with an object of their own choice. Establishing the context falls to the viewers of the exhibition and readers of the accompanying book – often with an element of surprise.

Unprejudiced approach

Showing diversity without prejudice was a major goal of this project. “We have tried to include as many places as possible, not only geographically, but also in terms of different subjects. Places of research, agriculture, defence or culture. Places that polarize society are also included, such as a halal abattoir or a darkroom. We made a special point of not leaving them out but giving them a place entirely without any ethical judgement instead”, the curator emphasizes. The photographs also serve as contemporary witnesses. For example, the radio play studio of the Swiss radio and television network lost its purpose due to digitisation and was demolished some time after the photos were taken. 

A continuation of the project is already planned, but in a different context. This context will not yet be disclosed, in contrast to the fundamental insight which Iselin and Maros have gained from the current project: “Regardless of how fascinating and well hidden a place or a trade may be, it is still a part of daily life for someone.”
