Understanding Photography as Applied Chemistry: Using Talbot’s Calotype Process To Introduce Chemistry to Design Students

Abstract

Early photography processes were predestined to combine chemistry and art. William Henry Fox Talbot is one of the early photography pioneers. In 2–3 day workshops, design students without a major background in chemistry are able to define a reproducible protocol for Talbot’s gallic acid containing calotype process. With the experimental concept presented herein, students can be taught to approach an issue in a systematic way, to practice their problem solving skills, and to experience chemistry in a hands-on learning environment. Students are coached individually in accordance with their progress. The students can understand the chemical process, manipulate it, and translate it into artwork. However, the molecular interpretation of a photograph is the means to an end. Photography is a well-known, ubiquitous process, and even today, young students are fascinated by the moment when the picture becomes visible in the dark room. Labor intensive photographs are appreciated in a different way than images taken with digital cameras or smartphones. Students succeeded in formulating a reproducible protocol for the calotype process and are able to pass on their knowledge to fellow students.
