Lichfield joined the Grenadier Guards in 1959. On leaving the Army in 1962, he began to work as a photographer's assistant, and built up his own reputation, partly as a result of having access to the Royal Family. He was selected to take the official photographs of the wedding of the Prince and Princess of Wales in 1981, and subsequently became one of the UK's best-known photographers. From 1999 onwards he was a pioneer of digital photography as a professional standard. He was chosen by the Queen and the Duke of Edinburgh to take official pictures of her Golden Jubilee in 2002.
