After some time drawing "funnies", Ranson drew on his skill in translating pictures across mediums (generally using a Grant Projector, which "projects an image up onto a glass plate, on which one places tracing paper"), and brought his talents to bear for Look-in by creating strips based on such popular TV series as Sapphire and Steel and Danger Mouse, all written by Angus Allan. Since these works were based on specific TV shows, he says that "it seemed important that the characters looked as much like the actors as possible", and thus "used the methods I knew" to achieve the accurate likenesses that typify his work.
