In his debut series “Metro Works,” Canadian photographer Chris M. Forsyth offered dramatic compositions, punchy colors, and total absence of people, and his striking shots of stylish modern subway stations in Berlin, Stockholm, Munich, and his hometown Montreal immediately caught the eye of magazine editors and social-media gurus. The photographs soon featured in international exhibitions and resulted in a spin-off book, “Stockholm Sub,” published in 2018. Faced with the challenge of following this tour de force, he’s pursued research-based projects exploring our complex relationships with place, linking together history and geography. Such projects include “Keep Direction by Good Methods,” which traces the remains of America’s transcontinental lighted airway system. Rich in content and imagery, switching between the monumental and the personal, his recent work contrives to be both beautiful and strangely moving.
