The postphotographic, as an inclusive concept bridging all the phases of digital photography, requires focusing on several levels: as a different technique of light, a different gesture, a different politics and science of the visible. A difference that is not an absolute novelty but rather the resurfacing of an original idea of photography, left on the margins for much of the twentieth century. The fifteen essays gathered here each explore an aspect of it, between past and future: photography as a method of tracing, a collection of invisible light, a technique for measuring the self and the world, a node of connections, a paradoxical object that is no longer necessarily seen, but nonetheless present, still capable of allowing a broadened participation in the world.
