Yeah, I’m the first to admit that recreating the look of theatrical prints is not really my thing, all the scans of film prints i’ve seen have had the colours way too muted for my taste, the Jurassic Park scan comes to mind for instance, I found the colours on that to be too flat and desaturated for my liking.
That said, Terminator is of course a very different film to Jurassic Park and this muted/faded look does fit it better. I like where you’re going with this and look forward to checking out the finished release.
