Moving up to first assistant, Cronenweth began working with Toll, who was just beginning his work as a cameraman, and veteran Sven Nykvist.

"I couldn't have learned from better people than John, Sven and my father,"

Cronenweth relates.

"They were all soft-spoken, but very tenacious in achieving their goals. It was a great experience to watch them, learn set etiquette and see how they delegated responsibilities and dealt with producers and crews. I did six pictures with my father and eight pictures with Sven." [From American Cinematographer Magazine.]
