Steinert, along with Peter Keetman, Siegfried Lauterwasser and Wolfgang Reisewitz founded a photographic movement in post-war Germany called Fotoform, which was aimed at the further engagement of the artist in his work through technical means such as the use of unorthodox viewpoints and experimental compositions and printmaking.
In The New York Times Photography Review of May 28, 1993, Charles Hagen mentioned Steinert's emphatic desire to build bridges to the work of pre-war photographers, which in several of his (Steinert's) pictures of industrial scenes, solarized and printed in negative... resemble other-worldly nighttime shots (that) recall Moholy-Nagy's earlier experiments with similar processes.
