In the rich history of photography, certain chemicals have left an indelible mark, and Pyrogallol (CAS 87-66-1) is undoubtedly one of them. While hydroquinone eventually became more common, Pyrogallol, or pyrogallic acid, holds a unique place, particularly for its distinctive properties in black-and-white film development. It's experiencing a significant resurgence among contemporary photographers seeking nuanced tonal control and archival quality.


Pyrogallol was a favored developing agent in the 19th and early 20th centuries. Its characteristic ability to stain the film's emulsion in addition to developing the silver image created negatives with enhanced sharpness and a unique tonal scale. This staining property also contributes to the archival stability of the negatives, a highly sought-after attribute for fine art photography.


The so-called 'pyro' developers, including modern formulations like PMK and 510-pyro, have revitalized interest in this versatile chemical. These modern iterations have largely resolved the consistency issues that plagued earlier forms, making Pyrogallol a reliable choice for those exploring alternative processes or desiring a specific aesthetic. When photographers consider pyrogallol in photography development, they are often looking for the distinct staining and tanning effects it imparts.
