General note

This colour television studio camera was one of two Phillips colour TV cameras on campus, and as mentioned, purchased in 1968. The cameras were located in the RTA television colour Studio B in Kerr Hall East, Room 225, which was converted to a regular classroom in 1991 when RTA moved to the then newly built Rogers Communication Centre. At that time, the cameras were decommissioned and Camera 1 was donated to Ryerson Archives.

The Phillips LDK 3 was sold around the world. In the U.S. and Canada, its major competitor was RCA. The built-in zoom lens on the front came from Angenieux of France and cost $40,000 back in 1966.

This camera had three plumbicon tubes (from the Latin word plumbum meaning lead) using lead compounds to turn light into electricity. The name was used to separate this European tube from the more common image orthicon camera tube which had been used for two decades in black and white television and continued on into the colour age.

To capture colour, the incoming colour image was interpreted by prisms (dichroic mirrors) which separated the image into red, green, and blue. The three plumbicon tubes received the red, green, and blue subdivisions of the image and scanned them to make an electronic version of the image. The three signals could be recorded and/or broadcast to television sets which reversed the process, illuminating the red, green, and blue phosphors on the TV screen, varying the intensity to create the colour image. This occurred 30 times a second to give the illusion of movement.
