Robert McLachlan is a Canadian cinematographer. A successful cyclist in his youth, McLachlan quit the sport to take up cinematography, and entered the field after studying at Simon Fraser University, McLachlan was mentored by Richard Leiterman. His professional career began with documentary work for Greenpeace, before he became involved in both television and feature films; his work has subsequently earned him several industry awards and award nominations.
McLachlan, who was inspired by both his father's photography and his own appreciation for the films Butch Cassidy and the Sundance Kid and Walkabout to choose his career path, would go on to find recognition as the chief cinematographer for the television series Millennium, for which he was scouted specifically. McLachlan's style on this series led to several industry awards and briefly became popular in the medium, as well as leading him directly to future work on Game of Thrones. He founded the documentary production company Omni Film Productions in the 1970s, later selling his share of the company.
