"Preparation of an internegative which closely resembles the characteristics of the original has always been the goal of optical houses throughout the industry. In spite of the superb quality frequently achieved in internegatives, it seems virtually impossible to attain characteristics identical to those of the original negative in the duplicate generations for the following reasons:
1. The non-linear response of photographic film limits the range over which the following generations can duplicate an original. The internegative is one or two generations away from the original, depending on the stock used.
2. Many variable elements are introduced during the processing of the internegative.
3. The exposure characteristics of the optical printer may vary from time to time.
1. so what, you're creating a new Zapruder film original.
2. so what, you're creating a new Zapruder film original.
3. of course as they do, ALL the time, and so what, you're creating a new original. The only given is that the new in-camera original (sic) deliverable is on 8mm KodachromeII ASA25, and attendant dupes are on Kodachrome IIA...
and its a far cry operating a some historical kluge Oxberry optical printer in Canada today, to having an entire optical film printing house complete with technicians, artists and post-effects directors available for your projects.... especially those experienced operators whom have no need for instruction manuals...
