Abstract : The report describes a study program which was concerned with the investigation of photographic image transformations. Samples of cloud photographs were digitized using a programmable light source (a computer controlled CRT scanner). The digitized data were then processed in various ways and subsequently applied to the CRT scanner system to generate mutated photographic images. The purpose of the transformations was to investigate effects and limits of: (1) variation of luminance levels, in both linear and non-linear fashion, and (2) varying image resolution. Fifty-seven (57) of the recreated photographic prints were selected as those images which best demonstrated the results and goals of this study. These prints, along with the associated pertinent transformation data are included as part of this report. This document is supplied in loose-leaf binder form such that the photographs may be readily removed to facilitate evaluation, comparison, and/or reorganization. (Author)
