For 20 years, Artur Walther will tell you, investment banking was his job, but photography was his life. Drawn more to bodies of work than to single photographs, Walther “invests” in artists instead of companies, and now has one of the largest and most important photography collections in the world. In this short film, Walther, a long-time ICP Trustee, explains his unique approach to collecting and sharing great photography.
