Photography, invented in the 19th century, revolutionized the artistic world, dethroning painting as the dominant medium of documentation and shaping new artistic understandings. Artists like Ernst Ludwig Kirchner integrated photography into their work early on, with Kirchner leaving behind a remarkable collection of over 1300 negatives and photo albums. In our exhibition, we place special emphasis on a series of images never shown before from the collection of the Kirchner Museum Davos: Some of the glass negatives exhibit traces of the artist's manipulation: areas of cross-hatching and linear figures were etched into the glass—a significant theme in Kirchner's artistic engagement with photography. His photographic work not only served for the precise reproduction of his art but also as a creative tool blurring the boundaries between documentary and artistic photography. The exhibition 'Ernst Ludwig Kirchner: Between Painting and Photography' at the Kirchner Museum Davos illuminates this unique connection, showcasing Kirchner's innovative use of photography as a precursor to his paintings and emphasizing the osmotic connection of both media in the hands of a masterful artist.
