Bulmer was one of the first photographers to adapt to the sudden change towards using colour photography for editorial photojournalism and one of the first to be employed by the Sunday Times Magazine when it launched in 1962. The professional relationship secured him a 60 page a year contract and had him travel to around a 100 different countries in over a decade on their behalf. The magazines first cover featured a picture of a footballer photographed by Bulmer surrounded by pictures of Jean Shrimpton’s armpit photographed by David Bailey.
In 1965, Bulmer first photographed the north of England in colour for the Sunday Times magazine. Using colour was Bulmer’s decision, as was the choice of winter or wet weather, when colour film was harder to use. Colour photography was a medium which Bulmer pioneered, ahead of such photographers as William Eggleston and Martin Parr.
The North has been exhibited extensively and acquired for private and public collection. A book of the same name was published by The Bluecoat Press in 2012 who subsequently published Wind of Change, a collection of photographs from some of Bulmer’s most important foreign assignments.
