 Friese-Greene was fascinated by the machine and worked with Rudge on a variety of devices over the 1880s, various of which Rudge called the Biophantascope.Moving his base to London in 1885, Friese-Greene realised that glass plates would never be a practical medium for continuously capturing life as it happens and began to experiment with the new Eastman paper roll film, made transparent with castor oil, before turning his attention to experimenting with celluloid as a medium for motion picture cameras.On 21 June 1889, Friese-Greene was issued patent no.
