Photographing with Bacteria

Zachary Copfer fotografiert mit Bakterien, auf Petapixel steht, wie's geht:

Here’s how Copfer’s method works: he first takes a supply of bacteria like E. coli, turns it into a fluorescent protein, and covers a plate with it (does this remind you something?). Next, he creates a “negative” of the photo he wants to print by covering the prepared plate with the photo and then exposing it to radiation. He then “develops” the image by having the bacterial grow, and finally “fixes” the image by coating the image with a layer of acrylic and resin.
