CALLE is a photographic/resilient project that gives people living in vulnerable conditions (street, shelters, homes, etc.) the opportunity to showcase their reality to the rest of the community through photographic images taken with mobile devices. The intention is to invert the usual logic in which they are "looked at" by society, to instead produce their "gaze" as they navigate the city, their usual circuits, and places of residence. The project has a significant archive of images, and a selection of 120 works have been edited into three volumes designed by Alejandro Ross and introduced by Eduardo Longoni. Several participants received training from professional photographers such as Juan Travnik, Eduardo Longoni, and Alex Gottfried Bonder.
