In 1961, all color at CCMTA was done using 4x5 film either negative or reversal. The reversal was Anscochrome and the negative was Ektacolor-S.
When Kodak released a new film in 1961, we evaluated possible use in 70mm format using a high speed camera. This was shot on 70mm in a Hulcher and is Experiment 61-75217, frame 84.
I was "producer and director" on this, choosing camera location, camera, and film.
