Colin’s photographs were mainly about urban life, metropolitan and coastal, and could be classed as social documentary. He demonstrated his eye for irony, combined with a professional competence. He won numerous competitions and has had many exhibitions, resulting in rave reviews and critical articles recognising his increasing status as a major exponent of the peripatetic school. Colin produced pictures for a number of photography books with associated bodies of work, in which poetic beauty was never lost, no matter how commonplace his subjects might seem.
