Cinema projectionists are, sadly, a dying breed, thanks to digital projection. Here's a very good, brief introduction to cinema projection, courtesy of the Phoenix Cinema, Finchley. It's the second oldest purpose-built, continuously operating cinema in Britain, having opened in 1912 (the oldest is the Duke of York's Picture House, Brighton). It features Peter Bayley MBE, the chief projectionist at the Phoenix, who has worked there for over 50 years.
