“Delicate Flowers” by Katia Weibel, Näfels, Switzerland
Parts used: Peels
Amount: Peels of 3 potatoes (2 handfuls)
Extracted by: Cut into small pieces
Solvent: Alcohol
Application: Brushing
Layers: 2
Substrate: Hahnenmühle Burgund postcard paper, 250 gms
Created with: Photogram of dried petals and leaves
Exposure: 20 days in May, spring 2026
UV strength: 5
Temperature: 20° Celsius or 68° Fahrenheit
Contrast: ✿✿ (Medium)
Challenges or observations: I also made prints with this same solution from digital negatives. Those were very weak in contrast. The petals, on the other hand, show rather high contrast.
Additional information: The full name of the plant is Potato (Solanum tuberosum), Var. “Blaue St. Galler”. I made several experiments with kitchen waste and hoped that the blue colour of this potato variety would show in the final print. However, the colour is in no way different from other potato peel anthotypes.

Potato (Solanum tuberosum) anthotype by Katia Weibel
This anthotype is part of World Anthotype Day
World Anthotype Day - celebrated annually since 2022 was started by AlternativePhotography.com. Our global community of artists celebrates the anthotype process by submitting prints. These works are added to our database here and compiled into reference books. The purpose is to build a large resource where artist can learn which pigments and plants work and draw inspiration from others. The reference books can be found here:

Volume 1 contains 60 unique anthotype emulsions from 103 artists taking part from 31 countries.

Volume 2 contains 100 unique anthotype emulsions from 139 artists taking part from 31 countries.

Volume 3 pushes the boundaries with emulsions not only from plants and pigments, but also from beans, moss and mushrooms. 135 artists shared their research.

In Volume 4 we will combine entries from both 2025 and 2026 into one beautiful double edition to include even more inspiring work, insights, and pigments to explore. The release for the combined World Anthotype Day book is planned for November 2026 – a richer, more comprehensive collection worth the wait.
