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.
