A wet plate cookbook

Wet plate photography is almost 200 years old, yet despite that age the process is still extremely variable and clear directions with results are hard to find. The goal is use my education in chemistry to refine and understand the variability of wet plate photography. For this project, I will be using the ambrotype (a specific type of wet plate) and will determine ISO (photographic sensitivity to light) experimentally, as well as the nuances of working with the medium. This project will make use of a Cadmium Bromide, Ammonium Bromide and Potassium Iodide salted collodion.
