Vandyke Brown: Extending the Life of Your Chemistry and Reducing Waste

Vandyke Brown is a relatively simple and accessible historic photographic printing process. Could a small change in the way you prepare and store your Vandyke Brown chemistry help it last longer and reduce waste? Brittonie Fletcher revisits this familiar photographic process and offers a simple rethink of the traditional workflow. Rather than mixing a larger batch that may eventually go to waste, this approach keeps things separate and mixes only … Read more

One Glacier, 200 Pieces: Making a Tiled Cyanotype

How do you make a cyanotype that is over 2 metres wide? Elizabeth Bourne broke her photograph of the Eqi Glacier into 200 individual sections, creating a tiled paper negative. She carefully numbered, printed, exposed, and assembled each piece to create one huge cyanotype measuring 209 × 109 cm. Using seal blubber oil, glacial runoff, and the Arctic midnight sun, she also found a way to connect the materials and landscape … Read more

Following Cyanotype Beyond the Print: Washwater, Waste and Material Responsibility

Cyanotype is often thought to end when the print is washed, dried, and hung on the wall. But what happens to the chemicals washed down the drain? Aindreas Scholz looks beyond the finished cyanotype to examine the washwater and waste. Through The Ecological Wetroom and a series of experiments, workshops and filtration tests, the project makes these usually overlooked by-products visible and asks how to become more aware of what … Read more

All 4 Lumen prints. From left to right: 5 minute exposure, 30 minute exposure, 2 day exposure and 2 months exposure.

Lumen Printing: How Exposure Time Changes the Image – from 5 minutes to 2 months (!) exposure!

Lumen printing is a simple cameraless photographic process where photographic paper is exposed to the sun. But the exposure time can greatly affect the result. Malin Fabbri shows how a short 5-minute print compares to 30 minutes, 2 days and – just to push the limits – an extremely long 2-month exposure time. See the difference! Writer and photography / Malin Fabbri Read the SDS (Safety Data Sheet) before attempting … Read more

Comparing cooked vs classic anthotypes

Raw or Cooked? Comparing Dry and Wet Anthotype Emulsions

Can a wet anthotype last longer? Anthotypes are known for their delicate beauty and their temporary nature. Made from light-sensitive plant pigments, they gradually fade over time, making impermanence part of the process. But what happens if the emulsion is exposed while it is still wet instead of allowing it to dry first? In this article, Chilean artist María Piedad Aguirre compares dry with wet anthotypes. She explores how different … Read more

A Non-Toxic Gelatin-acrylic Sizing for Gum Bichromate and Other Processes

Gelatin-acrylic sizing provides a reliable, non-toxic alternative to traditional paper sizing for gum bichromate printing. Marek Matusz explains how combining gelatin with acrylic medium improves adhesion, reduces pigment staining, and produces consistent multi-layer prints. He compares several formulas, recommends his preferred mixture, and shows how the sizing also works well for cyanotype, palladium, and gum-over prints. Writer and photography / Marek Matusz WARNING: ADVANCED USERS ONLY: This process requires experience … Read more

Hand Sanitiser + Cyanotype Transfers

Want to explore an experimental combination of hand sanitiser and cyanotypes? Julie Mixon shares an inexpensive, accessible way to expand the traditional cyanotype process by introducing photographic color, layering, masking, double exposures, and other visual effects. Learn about the challenges such as paper expansion and image registration, and try a flexible way to experiment with combining photographic images and cyanotype. Writer and photography / Julie Mixon Read the SDS (Safety … Read more

Soaking plants for eco printing

Eco-printing: How to Print with Leaves, Rust, and Heat

Eco-printing is not generally defined as an alternative photographic process, but a closely related printing technique. it shares the same spirit of experimentation, natural materials, and handcrafted image-making. It also combines beautifully with processes such as anthotypes, which is why we want to share it. Yulia Kapustynska shares her eco-printing process. Writer and photography / Yulia Kapustynska Eco-printing creates images through direct contact between plants, metal, paper, heat, and time. … Read more

Measuring cyanotypes without a scale

Measuring Cyanotype Chemicals Without a Scale – including Cheat Sheet

A practical guide to measuring cyanotype chemicals with teaspoons and tablespoons. Many cyanotype practitioners (I am one example) like to work with precise measurements and repeatable results using a gram scale, but beginners may not yet have invested in a gram scale. Fortunately, there is another option using spoons. I measured common kitchen measuring spoons filled with cyanotype chemicals 20 times each and calculated the averages. The results provide a … Read more

Impatient Anthotypes: High-Contrast, Quick-Exposure Emulsions

The anthotype process transforms everyday plants and food into beautiful, light-sensitive prints, but it is often slow and unpredictable. In this experiment, Mariam Matta set out to explore high-contrast, quick-exposure anthotype emulsions that could offer faster results without sacrificing detail. By testing a variety of plant pigments, alcohol thinners, and toners, she aimed to identify combinations that are both reliable and visually striking and shares the results in this article. … Read more

Building a Pinhole Camera and Making Solargraphs

For Worldwide Pinhole Photography Day, I thought it would be a good time to revisit the simplicity and potential of pinhole photography. It was a while since I made a camera, so it was nice to be inspired by Justin Quinnell’s pinhole resource and Heather Palecek’s article. Building a pinhole camera is very easy. Solargraphs require patience, but the result is a unique record of time and the movement of … Read more
