Portland, Maine-based photographer Caleb Charland combines art and science with his photographic experiments involving electricity, fire, and magnetism. One of his ongoing projects involves a series of alternative power sources created using fruit, coins, and even vinegar to power the lights in his long exposure photographs.
The apple photograph above involved a nearly 11-hour setup as he carefully hammered 300 zinc-coated galvanized nails into apples (zinc reacts with acid in the apples creating electricity, science!) and used copper wiring to transfer the current to a standard living room lamp. Even then, the light was so dim it required a 4-hour exposure during which Charland fended off ravenous deer through the night with an impromptu shaker made from a tin can and wire nuts.
