Re: How many prints were floating round in the 1960s...?
That's interesting: I'm trying to work out how using a larger film stock got round the practical problem that led to the suppressed field technique being used as a stop-gap (it takes time to move on the film, so the second field couldn't be shot as that was being displayed while the film was advanced).
