English artist Chris Bucklow is best known for his Guest series of solar pinhole photographs of luminous silhouettes. Unlike conventional photography, each image is unique and unrepeatable. He begins by making a life-sized silhouette drawing from the sitter's shadow on a sheet of aluminum foil, which is then penetrated with thousands of pinholes within the outline of the shape. These pinholes act as the camera's lenses.
Using a large homemade camera, he then places the foil on top and loads color photographic paper at the back. Sunlight is then allowed to shine through, recording many images of the sun and sky simultaneously, thus forming the shape of the figure on the paper behind. Bucklow achieves variation in the different works depending on the intensity of the sunlight, the time of day, and the duration the pinholes are exposed to the light.
