My portraits are held in the permanent collection of the National Portrait Gallery, London, and in the Royal Collection. I have photographed Sir Ian McKellen, Sir Patrick Stewart and Dame Judi Dench, along with five British Prime Ministers, Tony Blair and Theresa May among them, and I am a four-time winner of Portrait of Britain. What I teach at Samy's is exactly what I practise in those sittings. Nothing is simplified and nothing is held back.
