How can we develop photographic processes that are not based on a relationship of exploitation of the environment, but rather enter into collaboration with non-human actors? Even if such an endeavour must fall short due to the anthropocentric perspective, that impossible drift towards more plant-based thinking opens up a field of tension for artistic exploration. From strolling in the woods, collecting herbs to the ambivalence between urban space, plant periphery and ruderal vegetation – all those dynamic interrelationships of a shared habitat represent the intellectual starting point of the works of "Photosymbioses – On Co-Developing with Plant Accomplices". In addition to the effort to create a photographic gaze that fits into the mutual network of relationships of these co-existences, the research focuses on the imaging process of analogue, sustainable photography. This old technique, which is increasingly making a comeback in times of a flood of digital images, poses a number of challenges:
For example, this method of image creation is based on the light sensitivity of silver halide crystals, which are deposited in a gelatine emulsion on a film carrier (to produce the negative) and on paper (to produce the photograph). In order to convert the crystals into metallic silver and thus obtain a (negative) image on film, or then process and enlarge it on paper (positive photographic image), it is necessary to use various highly toxic chemical solutions. These products are not only hazardous to the health of those who handle them, but are also a major source of pollution of water, pipelines and the environment in general - and must therefore be disposed of and treated in a special way. Furthermore, it is not only the toxicity of this image development method that is problematic, but also its medium. The gelatine applied to film and paper is of animal origin - usually a bovine gelatine - and thus becomes part of the manifold problems of the meat industry. Ultimately, the industrialisation of analogue photography, from its chemical components to the development of the photos in laboratories, makes its users dependent on prefabricated, usually expensive products.


Driven by the desire to explore new experimental forms of creation and to reflect on the environmental impact of that photographic technique, various alternative methods for reducing chemical use were thus developed. In the process, various international initiatives from the field of sustainable photography provided inspiration for the production of own black-and-white developers based on regional and seasonal plants from Karlsruhe's urban environment (herbs, leaves, flowers, tree bark, moss, vegetables, etc.). The exhibited works provide insights into the experimental research, a complementary website gives further information on documentation as well as production processes and research.
