Hi’ @sankos
This color/profile business is really a complex issue. I observe the following in my dcp example:
Image part 1. Neutral processing profile, tone curve checked
The image is much lighter than the neutral profile alone. Tone curve lightens the image and boosts the highlights. Ok, this is an expected effect.
The colors become strange and reddish. Look at the yellow fields. Not good! Why?
Image part 2. Neutral processing profile, look table checked
Much like the neutral profile without the look table. What is the look table supposed to do?
Image part 3. Neutral processing profile, tone curve and look table checked
The reddish look caused by the tone curve disappears as by magic, the whole image pops and the colors become closer to natural, but much more vivid. Interesting and pleasing but not like real life.
Can these effects be explained and/or in any way anticipated
Thank you for reminding me of the luma mask facility. I remember now having read about this facility but I have only just downloaded 5.7.
