Vinten Model H 35mm intermediate film cinema believed to have been used in conjunction with Baird Television's system in Studio B at Alexandra Palace, London 1936.
A Vinten Model H 35mm film camera, England, c.1936, believed to have been used in John Logie Baird's television studio at Alexandra Palace.
In 1936 Baird used a system called the 'Intermediate Film Technique'. A modified film camera was used to shoot scenes in the studio. The film was fed through a hole in the bottom of the camera into tanks containing developer, fixer and then water. Whilst still underwater the developed film was then scanned by a special Nipkow disc to convert it into a television picture. The system was terribly unreliable and was dropped after 3 months.
