“Through The Green Fuse” is series of photos by Robert Buelteman, actually they are photograms. His technique is quite complex and dangerous, it’s based on Kirlian photography. He places flowers and leaves on a color transparency film, on top of that he lays plexiglas with a sheet of metal in between, floating in a liquid silicone. Then he hits everything with an electric pulse which causes the coronas and outlines to appear on the film. The last step he needs to do, is hand-painting it with a white light coming from an optical fiber. It can take up to 150 attempts to get this right. You can read more about it at Wired.
The results are just stunning.
