The exhibition "Light as Colour" offers the first review of coloured and colour photographic production on Slovenian soil from its origins in mid-19th century until 1945. Before the first colour photography techniques emerged in the early 20th century, photographs were coloured and toned after the developing process. The Museum of Architecture and Design also showcases the different process with which the photographers work to make their shots colourful.

Opening tomorrow at 7 pm, the exhibition opens a window to different age: when there were no digital cameras and no "shoot as much as you want". In the 1920s and first half of the 1930s photographers in Slovenia used the so-called Agfa colour plates, only about ten of them have been preserved. Only a handful of experienced people knew how to handle this kind of photo technique, that's why these photographs are so rare.

Most of the shots are not from professional photographers, but from different individuals who liked to experiment with the art of colour photography: pharmacists, engineers and journalists, they all experimented with the new possibility of making colours on photos visible, trying different light conditions and settings.

Since all of the photographic processes from the Autochrome plate onwards created transparencies and were therefore dependent on projection, the exhibition will also demonstrate the evolution of projection techniques from the magic lantern to cinematographs and slide projectors to epidiascopes, which were especially suitable for use in school lessons.

The exhibition was made in cooperation with various other Slovene museums, like the Museum of Gorenjska in Kranj, theMuseum of Modern Art in Ljubljana and the National Museum of Contemporary History in Ljubljana.
