This anthotype is part of World Anthotype Day
World Anthotype Day was started by AlternativePhotography.com in 2022. In August anthotype artists all over the world celebrate the anthotype process and send in their entries. We add them here to the database and create a reference book for each year. The purpose of the day is to build a large resource where artist can learn which pigmenets and plants that work and draw inspiration from other artists' work. The reference books can be found here:
