Extracted by: Mortar
Solvent: Isopropyl Alcohol 99%, 2 teaspoons
Application: Brushed on after straining with cheesecloth

Layers: 3 wet layers
Substrate: Fabriano hot press watercolour Paper, 300 gsm
Image Created with: One fresh rose petal, one fresh rose leaf, two dried pine needles and a bit of dried rosemary sprinkled on top.
Exposure: 8 days in early October 2026
UV strength: Uncertain, sunny days through a window

Challenges or observations: The next time I might try adding another layer or letting the ink dry before exposure, just as a comparison, but I am happy with the result.
Additional information: I enjoyed using a rose in this process. I saved the rest of it to use for cyanotypes. I like the shapes from the petals and leaves, both fresh and dried.

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.

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.
