A sheet of photographic paper with an emulsion much slower in its light-sensitivity than that used for typical darkroom-based photographic printing is laid out in sunlight and objects are placed upon it in any desired arrangement.  Given a five-minute exposure, the uncovered space on the paper around the objects (and, if they’re at all translucent and/or transparent, the areas beneath them) become visibly darkened by the sun.  The exposed paper is then processed with gold chloride toner to make the image permanent.  This solar photogram may then be exhibited as is or used in turn as a paper negative.  For the later purpose, one places it on top of a new unexposed sheet of the same light-sensitive paper and then exposes it to sunlight again.  The resulting image or “positive” print displays the reversal of the original paper negative’s tones and/or colors.  The varying intensity of sunlight throughout the seasons, as well as the infinite variety of forms in human and botanical nature, make each such print unique, providing the magic of the unexpected.
