Well, I know that's the party line, but to date I've never seen opticals/dupes match original negative no matter how much DNR and sharpening they slather on. Instead of grain, you get digital mush, and it still looks like crap compared to the shots around it. If really you want them to match, you should recomposite the opticals or use a better source. Even in film projection, opticals from 70s films still clearly
