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.

Photographer, Professor of Visual Arts and Ceramist Technician. He was born in Buenos Aires, Argentina. He trained in the city of Tandil at IPAT and at the Ceramic School. Upon completing his studies, he became interested in 19th century photographic techniques and began to research and experiment with them. He currently coordinates experimental photography workshops and alternative photographic processes in his virtual space “Sensitive Surfaces” and in the Ágora of the ExpFestival. Since 2023 she has been the director of the artistic residency at the Experimental Photo Festival (Barcelona). He has held several individual exhibitions in museums and galleries in his country. He also participated in group exhibitions and festivals in Argentina, Colombia, Ecuador, Mexico and Spain. He has published the mini books “MADER” (2014), “El Cuerpo Roto” (2019) and “Las Vías de Escape” (2020). His 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.
