Released September 2025.

Back to Basics: Extended Recipes for Ecological Photo Chemistry, is the second volume of Andrés Pardo’s research into low-toxicity photographic developers. Once you have mastered the foundations featured in Volume 1, this second volume teaches you that your photographic developers can slow down, be useful, and adapt. 

This book covers:

• Developing with rusted metal extracts.
• Food waste developers.
• Semi-solid developers.
• And much more!

Drawing on 10 years of research, this book is brimming with extensive recipes, formulas, and methods that make us consider what role we want our chemistries to play and how we can design them according to use.
