Creating Your Own Liquid Emulsions
for Black & White Paper
The Handmade Silver Gelatin Emulsion Printis a cookbook of simple, basic recipes for making black and white
printing paper and paper negatives, along with creative options for printing, toning, and coloring. Author
Denise Ross draws from photographic literature from the last 135 years, adapting old recipes to fit modern
tools, materials, and work spaces and modern twists have been applied to traditional techniques.
The book is divided into three sections: Section One lays the groundwork for this unique alternative
process; Section Two provides the recipes; Section Three highlights contemporary silver gelatin artists.
The book features over 200 full-color images and covers key topics including:
• Vocabulary: a list of terms used by traditional photographers and emulsion makers
• Creating work spaces with the right tools and materials
• Basic emulsion chemistry and paper coating techniques
• Working with various negative options, analog and digital
• Gaslight chloride contact printing paper
• Kodabromide-type chlorobromide all-purpose paper
• Bromide enlarging paper
• Warm tone paper and developers
• Making and toning your own printing-out paper (POP)
• Matte surface and baryta coating surface paper
• Paper negatives and making hand-drawn and digital masks
• Toning handmade paper
• Gum printing over handmade paper
• Troubleshooting handmade paper
• Artists working with handmade paper
The Handmade Silver Gelatin Emulsion Print is for photographers who love the look and creative potential of
black and white traditional photography but who want more control over the process and the end product.
It is written for the beginner to experienced photographer, with processes initially explained in such a way
that anyone will feel comfortable getting started, as well as information in increasing levels of complexity so
that experienced photographers who enjoy a challenge will also find one.
Denise Ross has been a photographer for over 30 years. Ross grew up with interests in both the arts and
sciences. Halfway through pursuing an MFA in photography she switched tracks and earned a master’s
degree in botany with an emphasis in wetland ecology and restoration. In the late 1990s, Ross retired from
botany and returned full-time to photography. Since 2003 Ross has been working with handmade silver
gelatin emulsions; she has been at the forefront of the handmade silver gelatin renaissance. Combining her
background in science, research, and love of traditional black and white photography, Ross has extensively
researched and reverse-engineered historic emulsion formulas and techniques for contemporary use. Ross
created The Light Farmin 2008, a teaching website devoted to the renaissance of handmade silver gelatin
emulsions. She has shepherded the public conversation and understanding of this field, and authored a book
The Light Farm, Handmade Silver Gelatin Emulsions for Dry Plate, Paper, and Film, Volume 1: The Basics
(2015). Ross’s work has been exhibited nationally and has appeared in publications such as Photo Techniques,
Large Format Photography,The Book of Alternative Photographic Processes, and Jill Enfield’s Guide to Photographic
Alternative Processes.To see her work, visit www.thelightfarm.com
Contemporary Practices in Alternative
Process Photography Series
Series Editor: Christina Z. Anderson
The Contemporary Practices in Alternative Photographic Processes series focuses the lens on a variety
of alternative, historical processes from the medium’s 180-year history. Each book outlines a
step-by-step approach to a particular medium, and features contemporary artists who use that
particular process regularly in their practice. The richly illustrated books in this series serve as
guidebooks for those new to alternative processes, refresher courses for professionals already familiar
with each medium, and a source of inspiration for all.
