Haydn has worked as a documentary photographer for over twenty years. He is based in South Wales, but has travelled world wide during his career. He has received numerous commissions along with British Council and Arts Council Awards to document communities and regions here in Wales, but also in other parts of the world such as Patagonia, the Arctic, South Africa, Palestine and the U.S.A. His photographs have figured in numerous exhibitions and publications and collections of his work are held at the National Library of Wales in Aberystwyth and Ffotogallery, Cardiff, Wales.

A photographic book of Haydn's work, titled 'Welsh Mod: Our Story', a series of photographic portraits of Mods in Wales, is available for sale at Welsh Mod: Our Story.

Haydn is available for documentary and editorial work, and also available for events, portraits and weddings.

"I think what's important as a photographer is not my personal experiences but the people that I meet and their story"
