EMI Emitron camera viewfinder
This rarely seen view of the ground
glass screen in the Emitron camera's viewfinder.
The optically formed image
was inverted. Red Cue light to the top right.
There is a discussion on the relative merits of optical viewfinders v electronic
viewfinders on pages 204 of "Television Engineering", by Amos & Birkinshaw,
pub. by ILiffe 1953.
