Too much black crush in many of the regrades, and you need to remember to lower the color saturation if you’re going to change the contrast so drastically.
As was explained in the first post, the purpose of this regrade is to replicate the original theatrical color timing. The reference is an unfaded 35mm print:
An algorithm is used to match these colors, including contrast and saturation, as closely as possible. This algorithm was developed specifically to replicate the color timing of a color reference. One advantage of this method, is that it avoids endless discussions on how a film should look, since what one person finds appealing, another finds appalling. As such, there will be no manual adjustments, as it is not the purpose of this regrade to improve on the theatrical color timing, as is established by the print. Prints tend to be more contrasty than the home video transfers we’re used to, but this is the way the creators originally intended the film to be seen on the big screen (within the confines of HD video). If this color timing is not to your liking, there will be a separate thread for regrading the original trilogy, to match the color timing of the 2003 DVD release.
