“#1” by Mary Brockson
Country: Wilmington Delaware, USA
Parts used: Seeds
Amount: 5 g
Extracted by: Ground in spice grinder and strained
Thinner: 2 tablespoons isopropyl alcohol 70%
Application: Brushing
Layers: 2
Substrate: Watercolour paper, 300 gsm
Created with: Photogram of leafy branch
Exposure: 8 hours, July 4, 2023 summer
Contrast: ✿✿✿ (High)
Challenges or observations: Faster result than expected
Additional information or observations: Thinning in water had no effect; tinting on paper had a moderate effect on 100% cotton (quilting weight) fabric which was dipped and soaked for 30 minutes. Brushing without straining resulted in a darker print, but a dirtier background that might be fixed by longer exposure.

Annatto seed of the achiote tree (Bixa orellana) anthotype by Mary Brockson
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.
