David has been documenting the faces of London's queer scene for over forty years and has captured some our most celebrated icons in his candid and intimate style. The National Portrait Gallery have twenty one  of his portraits and in 2017 they  marked  the 50^th anniversary of the partial decriminalisation of homosexuality with an exhibition of his work, Before We Were Men, which included the images of Leigh Bowery and Derek Jarman shown here.

In 2013 David was voted 16^th on the Independent's Pink List of the most influential gay people in Britain for creating the Pink Jack, the British gay flag, which was the first time a national flag had been 'queered'.
