The world's first photograph, the famous "window view" by Joseph Nicéphore Niépce, will be exactly two hundred years old in 2026. To mark the occasion, the Dresden Technical Collections are showing pictures by artist Thomas Bachler, who has been working intensively on the photographic process used at the time for many years. Heliography - or "sun drawing" in German - is a technique that is as variable as it is time-consuming, in which the image is created on a metal plate coated with asphalt under the influence of strong light. Heliographic images from the "A Glass of Water" series and heliographic intaglio prints from the "Gestalten" series will be on display in the exhibition.

A brochure will be published to accompany the exhibition.
