I’m gonna come across as a bit of a dick here so I apologize in advance.
I see very little difference between the TFA shots. Actually at first glance, I thought you had accidentally posted the same pictures twice. Wasn’t until I looked really closely that I could see the very slight change in the skintones. I guess if that minuscule difference is something that really bothers you then more power to you, I just don’t see how it’s a difference anyone could notice or care about on casual viewing.
No worries, you don’t last long as a regrader without developing thick skin haha. I don’t see anything dickish about what you wrote there though to be honest, until a couple of years ago I was exactly like you, I didn’t really notice or care whether fleshtones looked too red/green/blue, all I cared about was removing blanket tints, it was creating the V2 Star Wars Semi-Specialised Editions that really opened my eyes in that regard and made me a lot more sensitive to fleshtones. Now its the first thing I look at when regrading because fleshtones are actually really important. When a viewer is watching a film he/she actually spends the majority of the film focused on the faces of the characters which is completely normal, like our eyes gravitate towards a person’s face in a photograph, our brains are hardwired to lock onto faces. I completely understand where you’re coming from because I used to be exactly the same, that’s why i’ve been so surprised that the regrade for The Force Awakens has been as popular as it has been.
What I have noticed is a tendency to over correct. Yes, some of the skintones in the Star Wars movies are too red in their blu-ray versions, but a great many of the corrections remove virtually all of the red creating a very jaundiced look that is just as unnatural as the original red. TFA is particularly bad, but what I find the biggest issue with that one is that it is over saturated. So I very much think that all of these movies need to be corrected to remove some red, but not to the level that many do it. Leia in ANH should never look yellow. She should have a nice pink to her tone - about halfway between the above blu-ray and the offered correction. She seems to have the same skin tone as one of my coworkers. I still remember noticing several of our staff sitting across the table from me in indirect natural lighting and realizing how pink they were. A definite pink tone to the skin. Since I saw that, I have backed off my original corrections and approached it with a lighter hand and the results have been much more pleasing. I’ve also compared them to other movies and found that a lot of films have similar tones.
