Photographer Binh Danh calls this set of photographs “Chlorophyll Prints” for their obvious association with leaves. The experiment started when Danh noticed that leaves on the grass under a water hose and those directly under sunlight were of different color. The process isn’t all that easy though, and requires a fair amount of work and careful watch to actually come across as the prints we see.
Here’s what NPR says about Danh’s process:
From start to finish, his technique is this: Binh Danh begins by picking a leaf — often from his mother’s garden. To keep it from drying out, he fills a small bag with water and ties it to its stem. He places the leaf on a felt-covered board, and puts a negative directly on the leaf (he has an archive of images he’s collected from magazines and purchased online). He places glass over the leaf, clips the glass and board together, and puts the assemblage on the patio roof.
Binh Danh will check the image periodically to see how it’s “baking.” The process can last days or weeks. Four out of five times, he’s dissatisfied, and throws the leaf away. But when the chlorophyll print is right — whether precisely rendered or eerily vague — he takes the leaf, fixes it in resin, and frames it.
