Christopher Bucklow is a pioneer in the ‘cameraless’ photography movement. His project Guests is a series of images created using an unusual (and symbolic) photographic method.
Danziger Gallery describes his process:
His other-worldly photographs of radiant men and women set against grounds of color are made through a multi-step process that is both complex and laborious. 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.
