For many years, Thomas Ruff has been exploring the origins and history of photography in his series. In doing so, he has always questioned the significance of the actual starting points of photography and its essence. In contrast to painting, physical phenomena of optics – such as light, refraction or radiation – and their fixation on a medium always play an important role in photography.

The aim of his latest series expériences lumineuses is to examine this more scientific aspect, consisting of light, light rays and glass, more closely and visualise it with the help of ‘simple’ photography.

As he wanted to use ‘only light and glass’, he initially used a lamp and a glass prism to photograph rays of light and reflections that appeared on a rough concrete floor or on various white papers. However, as he was not convinced by the results, he decided to photograph the play of light on a shiny surface in order to make the rays more visible.

For this reason, he created an experimental set-up in his studio with the help of a multi-beam lamp and various glass bodies, which is used in physics lessons on the subject of geometric optics. In these demonstration experiments, light is projected through glass bodies arranged on a whiteboard. Depending on the nature of the light source and the glass bodies, light reflection, refraction and parallel, divergent or convergent light beams can be visualised.

Initially, he only had one lamp, which cast narrow or wide beams of light onto the surface depending on how it was used, but more lamps were subsequently added in order to multiply the lines of light refraction and make them more complex. The different light – from narrow rays to wide light beams – was channelled through various glass bodies such as cuboids, triangles, semicircles, concave and convex lens shapes as well as through different mirrors. The resulting light traces and reflections were unpredictable, but could be determined by arranging the lights and glass bodies.

For Ruff, this was ‘playing with the rays of light and the arrangement of the glass objects from which the light is refracted’ before he pressed the shutter release.

Ruff inverted the images of the optical phenomena so that the path of the light beam through the glass body into the room could no longer be perceived as light, but as a line or stripe. The progression of light, refractions, reflections and the glass bodies were thus transformed into almost abstract drawings that have left the realm of the natural sciences. To emphasise the painterly-graphic quality of the images, Ruff had them printed on primed canvas and presented them as large-format drawings in the exhibition space.
