The effects of chemical toners on cold and warm tone photographic black and white fiber base enlarging papers

摘要

What this thesis attempts to present is a systematic and ordered assembling of different true chemical toners on two types of black and white enlarging papers with two different developers. It is my hope that this study will be of some use as a reference in what effect it is possible to achieve with different combinations of toners, papers, and developers. Although not all possible combinations have been tried, most color choices are represented and I decided to display the same image repeatedly. A conventional paper developer, Kodak Dektol, as well as a developer of somewhat higher quality with a Glycin base, GAF 130, were used. Each respective thesis has its own enlarged and toned black and white photographic prints. An attempt has been made to try to report results clearly and factually, and to try to keep this paper as visual as possible. All toners are found with their respective formulas and all information necessary to duplicate results is supplied. I felt it was necessary to display the real effect of toners upon modern photographic materials because of their inherent capability to alter a convectional black and white photographic print. This alteration will ultimately affect the response of the viewer through the emotional impact of color.
