Is using an HDR monitor really the best way to color correct non-HDR sources? I fully admit i have no idea, but it sounds to me like maybe you shouldn’t be using that as a color correction monitor.
For a start I can’t even run the screen in native resolution as I have nothing 4K to put in or any HDMI 2.0 devices.
Rocky Horror is perhaps a good benchmark for the right time 1975 and how a good restoration should look.
This was quick in Gimp but Master Brightness and Contrast about +23 on both to bring this up to the same sort of level as Rocky Horror.
Before Brightness Contrast change. But Hue Shifted.
Original GOUT image color
As you can see I don’t want to do an awful lot to it anyway. This is basically the complete process of what I want to do. Apart from fixing the parts where the GOUT is no Good I plan to use the 97 Laserdisc.
Swingback on Cyan reveals Blue and Red Vader Chest Plate…Also notice the weird staining disappear on the left of the screen. This is about 45% out on hue for Cyan.
Here is my original Gout Shift
The process I am thinking of employing is the Purple swing back as well as the Brightness and contrast. This will be done via Selective Correction I also added some yellow in the Shadow here.
Basically I will do what ever I think it needs to get it looking better. Another Cyan Stain on the left mind you… It might be 45% in opposite direction this time?
