Digital Photography: An Introduction

In addition to their connection to space and time, silver-based paper photographic processes, from calotypes to chromogenic color prints, possess a subtle yet distinguishing visual depth that is diƒcult to duplicate digitally. e image of a gelatin silver photograph is formed on the underside of the top gelatin layer, which means that the physical image resides between the top surface of the paper base and the underside of the top gelatin layer. is creates a purely photographic look that allows you to “look into” the print’s surface because of the way the light reects and refracts within the silver particles of this sandwich. Sometimes called transparency, this look visually contains the image and objecties the views, helping to promote the notion that believability is built into photography. In contrast, digital imagery, with its reliance on inks and resolution, is more akin to the mechanical reproduction processes of relief printing, engraving, and etching. Images made from these processes rest on the top of the surface and therefore remove a sophisticated marker that historically made silver-based photography a surrogate for truth.
