Articles of Glass, 1844. Pursuing such diverse interests as language, mathematics, botany, and optics, William Henry Fox Talbot was a prominent scholar and scientist. In 1839, he invented the first system of positiive and negative photography---the calotype process. The basis of all modern photography, the calotype's paper negative made possible the infinite reproduction of prints from a single negative. In Articles of Glass, three rows of sparkling glass objects are isolated against a dark background, illustrating the new medium's ability to capture the nuances of light and record reality. A remarkable technical and aesthetic achievement, the image testifies to Talbot's artistry and classical sensibilities, expressed through his use of symmetry and a central focus. This image was included in Talbot's The Pencil of Nature (1844), one of the first books illustrated with actual photographic prints.
