John Treays

John Treays provided the studio lighting for The Daleks (uncredited, with Geoff Shaw) and Marco Polo.

Treays only worked on the first 4 episodes of Marco Polo because he had a falling out with designer Barry Newbery and said he couldn't light Newbury's complex sets. On episode 4 Howard King was brought in to work with Treays and completed the remainder of the story by himself.
