The photographs here were printed from multiple negatives, and some of the negatives themselves were already double- or triple-exposures done in-camera. "Glass Eyed" is the simplest: one 35mm negative of a brick wall shot through a transparent object, overlayed during part of the printing exposure with an 8x10" negative which, through years of neglect, has accreted an extra layer of what appears to be a geometrically-aware brown fungus. How many layers is that? Digital image blending may already be on the road to making some of these optical techniques seem antiquated. But the electronic image will no more kill the chemical photograph than photography killed painting.
