About the workshop
In this workshop we will see two techniques that use the photosensitive properties of different materials of plant origin. With antitype, pigments of different colors can be produced and applied to paper or fabric. In the case of chlorophyll printing we will use green leaves as a support. When light passes through a positive printed transparency placed by contact on a paper covered with vegetable pigments or on green leaves, it will react by lightening, allowing the images to be seen on these surfaces.
1- History of the technique and current references. 2- Preparation of work positives. 3-Plant extracts. Color possibilities, modifications with alkaline substances. Fading. 4-Possible supports. 5- Exposure times and light quality. 6- Choice of materials. 7-Conservation of copies of chlorophyll

Upon completing his studies, she became interested in 19th century photographic techniques and began to research and experiment with them. She currently coordinates experimental photography workshops and alternative photographic processes in his virtual space “Sensitive Surfaces” and in Ágora, School of Experimentation. Since 2023 she has been the director of the artistic residency at the Experimental Photo Festival (Barcelona). She has held several individual exhibitions in museums and galleries in her country. She also participated in group exhibitions and festivals in Argentina, Colombia, Ecuador, Mexico and Spain. She has published the photobooks “MADER” (2014), “El Cuerpo Roto” (2019) and “Las Vías de Escape” (2020). Her work mainly addresses the autobiographical, the self-portrait, the editing of photographic fanzines, the telling of stories in images about the body and illness, family ties, as well as experimentation with materiality, supports and different techniques without being limited to old processes.
