I recently watched 4K83 version 1.3 and really enjoyed the color timing and grading which was strikinly beatiful. Return of the Jedi has never looked so great before. Also, the minimal DNR makes a good job creating visible but smaller grain as probably would be expected from a camera negative.
Keep up the good work Team Negative 1!
Tomas, compare 4K83 v1.3 with v1.0 in scenes like Han out of carbonite - see the unnaturally pepper-red face of Han Solo? As I said before, most of the color corrections on the 1.0 versions of the 4K projects (1.1, …) tend to fix one scene /shot while making the next one worse. We’re still with no definitive, best version of either 4K77 or 4K83 right now.
Edit: u could also compare that scene with the official blu-ray version. Neither 4K83 v1.0 nor blu-ray make Han look so red.
