The themes Parr selects and his inimitable treatment of them set him apart as a photographer whose work involves the creation of extensive series. Part of his unusual strategy is to present and publish the same photos in the context of art photography, in exhibitions and in art books, as well as in the related fields of advertising and journalism. In this way, he transcends the traditional separation of the different types of photography. Thanks to this integrative approach, as well as his style and his choice of themes, he has long served as a model for the younger generation of photographers.
