Scanography is essentially a photogram, a subject placed on a flatbed scanner.
Reminiscent of a time when photographers made contact prints on a contact printer using AZO paper. The photographer would expose the paper by setting the exposure time on the printer, push the start button and the print was exposed. The photographer would then develop the AZO paper in dektol, and place the paper in a solution of 28% acidic acid to stop the development of the print, fix the image, and then wash & dry the print.
Today in the digital world these images can be created without the use of a camera just by placing the subject on a flatbed scanner and scan set to the desired dpi (dots per inch) or to the desired print size.
