Chemistry of Photography

~60 min · 15 stations

Chemistry of Photography is a self-paced learning path in Chemistry & Molecular Science, free to read, written at General Public / 9th Grade reading level. Across 15 structured stations, you will work through the core ideas step by step, each with a short quiz to check your understanding. By the end you will be able to identify the interaction between photons and chemical compounds; describe the crystalline structure of silver halides; explain the purpose of gelatin in film.

Conductor

The Conductor

All aboard for a journey through the chemistry of light! We are developing the hidden images within the film to reveal the science of the photograph.
