Andre Kertesz, Watching From Above

From his window perch, Andre Kertesz captured candid moments where his subjects were unaware the master photographer was watching them.

A new show at the Stephen Bulger Gallery in Toronto titled “Surveillance” seeks to answer that question, featuring photographs Kertesz, who died in 1985, made using telephoto lenses, or at times a telescope attached to his camera. The show takes a photographer known for his still lifes, portraits of artists, and later work from his apartment overlooking Washington Square Park and places him on an entirely different stage.
