In this episode of Unlocked, we speak with Mexican photographer and artist Alejandro Cartagena about the evolution of photography, from analog to digital and now into the age of artificial intelligence. Drawing on over two decades of practice, he reflects on the city as a force shaping identity, the role of archives and reproduction, and why AI marks a critical moment of transformation rather than the death of the medium. We also discuss Fellowship, the platform he co-founded to rethink photography, digital art, and collecting.
