When I began to work with film professionally in 1987 we had an ARRI KM 35, a copy of the Debrie Matipo, besides a couple Bell & Howell C and J at the lab. That printer employed a perforated 35mm Leatheroid band actuated by a maltese-cross movement. Circular apertures were punched out of the band and subtractive filter sheets stapled on. Timers would hold up snippets of a production against a light box, one hand on a wooden filter cabinet, and go “0.05 minus blue” and “0.25 plus green”. Wratten filters are still available. That is the old system. Short bands were assembled, eight frames of every scene from the dailies. In black and white they proceeded incredibly fast. I don’t know who is still alive of the timers I have met, Dietrich von Holten, Johannes Anders, Hartmut Engel, Fritz Windisch.
You have a time before and a time after the Hazeltine film analyzer.
