Scanography, also spelled scannography more commonly referred to as scanner photography, is the process of capturing digitized images of objects for the purpose of creating printable art using a flatbed "photo" scanner with a CCD (charge-coupled device) array capturing device. The term scanography formerly referred to medical scanning, but is unrelated in either purpose or technique. Fine art scanography differs from traditional document scanning by using atypical objects, often three dimensional, as well as from photography, due to the nature of the scanner's operation [1] Make Your Scanner A Great Design & Production Tool.
