In June 2018, a few of us visited the Bishopsgate Institute and rummaged through the past of London community darkrooms. We were very lucky to be guided by community activist and photographer Philip Wolmuth, who set up the North Paddington Community Darkroom (NPCD) in the 510 Centre, in 1976. The NPCD was later known as Photoworks Westminster. When they had to close down because of funding cuts, the Gate Darkroom was born as Lee and David-who were members of Photoworks Westminster then- were passed on some of the enlargers and equipment to start a new darkroom.
