I don’t think Lowry is to blame for ANH. I believe the issues with magenta are mostly caused by fading of the negative, which were then exasperated by a dodgy color grading. At the time of the original SE release, they showed some clips of the unrestored negative, and it had faded to a bluish green. In other words red had mostly faded away, and blue to an extend as well. When they restored the colors, the noise in these two channels was also enhanced, leading to magenta noise in the film. They applied DNR to it, resulting in magenta staining. So, I believe that any future release based on the original negative will have the magenta staining to some extend. This is why Mike Verta’s resoration is so unique, as it is based on prints, that don’t fade, and therefore don’t have these issues.
