Mark Hirsch is a 52-year-old photojournalist who happens to be friends with a tree — specifically, a towering bur oak on the edge of a cornfield in southwest Wisconsin. This unique relationship began on March 23, 2012, when Hirsch photographed the tree with his new iPhone, during a particularly impressive sunset. That test of new technology turned into a yearlong documentation, and a personal transformation.
