Today in class I will be demonstrating scan-o-grams (which are a take on photograms but made on a flat bed scanner instead of in a wet darkroom). Stan Sherer taught this in a class I took with him and I thought it was pretty effective. In honor of the disappearing photogram I have shown the work of Adam Fuss (see above). He makes lots of wild images using just photographic paper and objects (no camera).
I also found some scan-o-grams by a professor I had at SUNY New Paltz named Carmen Lizardo (below). I remember her being pretty awesome and never forgot these pictures that she showed us in her Design class.
