Catalan photographer Jonàs Forchini explores the ocean depths as a terra incognita, where the image becomes an unsettling experience. Far from the modernist codes of transparency, he develops a practice of “immersion” at 20, 30, or 40 meters, where the body, the water, and the photographic act merge into a single medium. His opaque, enigmatic images do not aim to represent but to disrupt our visual and mental habits. The book offers a sensory and contemplative journey, inviting us to relinquish certainties and reconsider our relationship to the world in an era of ecological crisis.
