While the building itself will definitely become a new landmark and a center of touristic gathering thanks to its unusual form, it also bears an incredible concept of creating a real "camera obscura", grandmother of Photography, with the mission of documenting and providing a better understanding of Seoul's history and the way it has managed to balance innovation and tradition. The "camera obscura" rooftop installation will function as the biggest "camera" on Earth and will be translating skyline of Seoul's city view at the exhibition rooms and at the top of the exhibition area.

The project designer Öznur Pınar ÇER says "This project aims to create a new experience for visitors by creating a "camera obscura" installation on top of the museum's roof and exhibition rooms… bringing together a synthesis of ancient and new technology that adds value to the Seoul photographic art museum's mission of entertaining while educating its audience."

"MASK architects" claims on the official website: "The combination of education and entertainment also brings the history and future of photography in the same place and at the same time in a way that will make the museum's building a perfect synthesis of past and future that we find is a thriving value in contemporary Seoul."

Technically, the "camera obscura" works thanks to the two lenses and a large periscope mirror that were installed on top of the building. Its closable and openable system enables the area to become dark by closing the pinhole for a dark atmosphere for exhibition.

At the top of the roof surface on the west side, a mirror is used to reflect the inverted image to display sky images on the middle of the gallery space. The mirror can be automatically controlled, so the interior of the cloud chamber has trees, clouds, and blue sky projected across the white cement walls. At the top of the building, the designers mounted a plain mirror, protected by a hood and a window-pane. The mirror is angled so that natural light reflects downwards into the tower. The light will pass through three lenses, bringing the focus onto the gallery space. The lenses also switch the sky view so that it appears upside down on the gallery space.

With the help of the described technical and designing solution, the whole building turns into a giant "camera". The "camera obscura" will project the wide sky that could be seen from the roof. It can also be used on other surfaces of the building, which would allow the camera to show Seoul's urban landscape across the gallery space. Now, just by walking on the gallery space that is in the center of the building, visitors can experience in real-time lively scenes of the surrounding Seoul city.

However, not only the "camera obscura" device makes the building special and attractive. The exhibition of the museum itself will comprise of optical illusions, puzzles, etc., providing guests with an incredible opportunity to experience tricks for the mind, feel all the senses. Gamification will be a key element of these exhibitions. The visitors will not only be able to walk in the clouds. The will all get inspired by the exhibition which will be created based on the rule of gamification –unlike a lot of learning centers, there will be nothing in this one you are not allowed to touch.

The museum rises up to 22 meters in height and covers an area of 84.5 sqm. The building itself is also worth describing. It has an unusual, wavy, trapezoidal shape, different from every angle. The architects aimed to unify fluid forms, daylight, and lighting at the museum design. Linear louvers of aluminium outer cladding filter the sunlight, ensuring a soft light for the structural curves. However, the metallic and shining cladding also features the special exterior lighting: thousands of light pixels on the surface remind the audience of a dream-like starry sky when they shine at night.

The main structure of the photographic art museum is made of reinforced concrete core, steel space frame structures for the main frame and composite beams and decks. The outer cladding, as already mentioned, is made of rectangular of silvery aluminium cladding panel with joint lighting elements for the exterior lightings of the building.
