Photo of Sussie Ahlburg, supplied by the Metropolitan Police
The body of Sussie Ahlburg, 50, was discovered in the women's bathing ponds on Hampstead Heath at around 2.30pm on Monday.
The Sweden-born photographer had been reported missing by her family after failing to return home on Sunday.
Detective Sergeant Trevor Plumb of Camden CID said: ‘Sussie's death is being treated as unexplained but we are keen to speak to anyone who may have seen her around the ladies' pond during Sunday 4 August.'
Police believe that the photographer, who was wearing a Speedo swimming hat and goggles had travelled to the pond using a folding, black, Brompton bicycle.
Born in Stockholm, Sussie Ahlburg took up photography at an early age.
The photographer's work has appeared in numerous publications including Vogue, The Times, The Guardian and The Wall Street Journal.
As well as a portrait photographer, she specialised in capturing images of jewellery, glass, fashion and textiles and, among other books, was the author of a guide called Photograph your own Art and Craft.
After moving to London she studied at the Central School of Art in London.
Sergeant Plumb added: ‘Anyone who has any information or who was in the area at the time is asked to call police on 101.'
