Flow Photographic Gallery was established in 2019 by photographer and printer Alex Schneideman to present the work of British and international documentary photographers. It operates alongside Flow Photographic, a print studio founded in 2004.

The gallery opened with Art London, featuring portraits of artists including Tracey Emin, Grayson Perry and Gillian Wearing, and has since presented exhibitions by photographers including Paddy Summerfield, Matthew Finn, Ian Macdonald, Jem Southam, Barbara Bosworth, Deanna Dikeman and Judith Black.
