His funeral was attended by John Hume and Martin McGuinness, and Ian Paisley led tributes to him in the Belfast Telegraph following his death in 1996.
His photographs were published throughout the world at the height of The Troubles. His discretion and integrity earned him the respect of both sides in the conflict. Carson was an author of several books about life in "Derry Derry Thru The Lens", "Yesterday..", "A Decade and a Half" and "So this was Derry".
A definitive posthumous collection of his photographic work named after his first book of 1976 - Derry Thru The Lens: Refocus - was published in 2006 by the Guildhall Press.
From local photographer he, along with many others, was catapulted onto an international stage. Photographers from all over the world visited and stayed at his home, using his back yard dark room to process their films and his front room to dry their prints.
As he recorded the horrors of the so-called "troubles" Carson also continued to capture the life of the city that continued beneath the surface of international headlines and the changes wrought by redevelopment to the streets around his beloved birthplace, the Brandywell. In the 1990s he began to think of another publication of his pictures bringing his work into the present day but died before he got the time to fully realise his ambition.
