Glowing Silhouettes Made of Thousands of Sun Streaming Pinholes.  “Bucklow begins by projecting the shadow of his sitter on a large sheet of aluminum foil and tracing its outline. He then makes about twenty thousand small pinholes in the foil silhouette (one for each day of the average human lifespan). Using a contraption of his own device that places the foil over a large sheet of photographic paper, Bucklow wheels his homemade ‘camera’ out into daylight and pulls the ‘shutter’ to briefly expose the paper to direct sunlight. Thus each finished picture becomes a kind of photogram silhouette composed of thousands of pinhole photographs of the sun. The intensity of light on a given day and the length of exposure create unique color variations on how the resulting piece appears.”  Christopher Bucklow
