Accompanying the publication of PhotoResearcher No. 37: “Three-Colour Photography around 1900” (guest-edited by Hanin Hannouch).

Three-colour photography is the basis for most colour photographic technologies nowadays, so why does its multifaceted history, especially at the turn of the last century, remain ignored by historians?

This online symposium complimenting PhotoResearcher No.37 delves into key technological, cultural and political questions pertaining to this medium in its various historical manifestations. Speakers will address issues of the scientific use of three-colour photography, its iconic protagonists, and its most representative imperial and colonial expeditions. They explore the multitude of photographic processes the term “three-colour photography” encompasses, ranging from Color Paget, Sanger-Shepherd, Miethe’s System, Bleach-Out methods etc. along with the material and epistemological conditions which engendered them.

This Symposium seeks to remedy the historical and theoretical vacuum around three-colour photography, opening exciting avenues for subsequent research and enabling more sensitivity towards the presence of colour photography in museum archives.

This conference is free of charge for attendees and all presenters have been offered an honorarium. This is made possible thanks to the financial generosity of the Photographic Historical Society of Canada.
