Edgar Lissel is a German artist who has worked extensively with different types of photography, including pinhole cameras and the camera obscura. Since 1999, he has worked with cyanobacteria, using their phototropic properties to produce images. After a complicated cultivation process, the microorganisms are prepared for image production in petri dishes. Filled with a bacterial suspension, the petri dishes are exposed to a light image for a period ranging from many hours to several days. The bacteria move out of the shadowed areas into the light and grow into the projected image.
