[...] The film was not just printed darker, or with muted colors, as some think. There are two sections of the original negative that were removed from the cut and assembled camera negative. One is the long shot where the cab pulls up, Bickle walks over to Sport, they argue, he shoots him, then he walks back and sits on a stoop. That is all one shot that was removed. The second section removed begins with the shot of the interior of the apartment building where he shoots the hood in the hand and all the shots following this down to the final one of the overhead crowd shot outside - that entire sequence was removed as assembled. These two sections of original camera negative were then sent to TVC, a small lab in New York, where it went through a Chemtone process, a chemical treatment that somewhat opens shadows allowing for greater density and lower contrast, for the most part. The exact process was a bit clouded by TVC as a proprietary service, but it usually involved original processing and, at this point, the negative was already finished. Whatever the actual processes, what I can say is that they delivered back duplicate negatives of these two sections, with the long sequence, in effect, now an optical dupe and with the desired color and density built into it. So, literally, when printing this film at a lab then (or now), there was no way to grade it and print it the way it was shot. Those muted colors are built into the dupe negative and it doesn't work to try to print it otherwise. We also searched many times over the years for the original negative that was removed, but to no avail. Likely, it was junked at TVC at the time.
