“Nasturtium” by Justine Kaemmerlen
Country: San Francisco, USA
Parts used: Petals from medium-orange flowers (not the deepest orange possible, but also not the lightest the plant produces)
Amount: 2 full flowers for a 4 x 3 inch print
Extracted by: Mortar and pestle
Thinner: 91% isopropyl alcohol
Application: Brushing
Layers: 3
Substrate: Watercolour paper
Created with: Photogram of dried and pressed nasturtium flower
Exposure: 4 hours, August, summer 2023
Contrast: ✿ (Low)
Challenges or observations: The bright orange petals crushed in a mortar and pestle mixed with some rubbing alcohol created a sunny golden yellow color that resulted in a final print fairly quickly, considering it was a partly cloudy day during exposure. I am impressed by the level of detail captured by this emulsion since it is yellow; typically, yellows are tricky when it comes to contrast in general.
Additional information: I am very excited to continue exploring the world of anthotypes as I dive deeper into my alternative photography process. I am hoping to use some native California wildflowers in upcoming experiments!

Nasturtium (Tropaeolum majus) anthotype by Justine Kaemmerlen
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.
