Zachary Copfer self-coined the above photo as bacteriography. By growing genetically altered bacteria in a petri dish as his photographic film and then exposing parts to UV radiation as his light. Through this method he can literally grow the photograph. Copfer then refrigerates the bacteriograph, uses another blast of radiation treatment to kill any microbes, and then seals it with a layer of acrylic to fix and preserve the image.
