Schmid studied Visual Communication at Fachhochschule für Gestaltung Schwäbisch Gmünd and Berlin University of the Arts from 1976 to 1981.
Living near one of the largest flea markets in Berlin, he had already amassed a rich, deep, and varied collection of vernacular photography which formed the raw material for many of his works.
[2] Schmid's use of extended series reflects his concern with photography as an encompassing, culturally dispersed and ubiquitous social and aesthetic discourse that runs throughout the public and private spheres of modern life.
Yet the fundamental richness of Schmid's photographic raw material – along with the sardonic wit he so often displays – derails any attempt to read his work as pure anthropology or social science.
At Rencontres d'Arles in 2011, Schmid was one of five curators (along with Joan Fontcuberta, Martin Parr, Erik Kessels, and Clément Chéroux) to sign his name to the From Here On manifesto, announcing a new age of photography as represented by 36 artists from around the world.
