I discovered Douglas' work by chance, googling for images of the Isle of Sheppey - either in preparation of a trip or shortly afterwards; one of his images of Shellness beach immediately stood out from the others. Following the link I discovered an extensive archive with work of considerable quality - fed by numerous excursions into estuarian territory. He contributed to and collaborated with the Museum of London's 2013 Estuary exhibition (which I sadly missed), leading photographic field trips to the landscapes that informed so much of his work. 

Now living across the Channel, in a country with an equally, if not more fragile relationship with the sea, he continues to make great work; please visit his website for more.
