Thanks for the answer, Jacques. I appreciate your help.
To study and learn from what others do I have two installations of dt3.3. One is for editing and one for examining the development of the xmp of interest. For anyone who is interested in trying that, it is important that in settings for the second, examination installation, under storage/xmp, un-check: write sidecar files for each image.
I have been going through your xmp and matching the settings on my own xmp. As I go, I compare the look of the photo images and also the histograms and the module tooltips of settings in the history. I use the waveform histogram. Everything goes well until I set up color balance, although there are some small discrepancies between my tooltips and yours earlier.
The tooltip for white balance for your xmp is:
while mine is:
I don’t know where the emerald nan setting comes from, therefore I can’t understand the difference. As far as comparing the images and histograms at that point, I can’t see any difference.
Later, for filmic your tooltip is:
and mine is:
There is a very small difference in white relative exposure, and a bigger one with hardness. Since that is auto-set, there seems to be nothing I can do about it, but the fact that there is a difference would seem to indicate something different about the images. Your tooltip says you are using the 2019 version of the spline generator, although in the filmic settings, color science is set to v4(2020). At any rate, I detect no difference in the graphs, nor in the photo images and histograms.
Coming at last to color balance, at this point obvious differences in the images and histograms appear.
This is your setup:
Mine is exactly the same.
Your tooltip and mine to the right of it are:
lift[0] appears to be 1+lift factor, which corresponds to gamma[0] and gain[0].
lift[1] appears to be 1+lift saturation, while lift[3] is 1-lift saturation.
Your gain[1] appears to be 1-gain saturation , while my gain[1] doesn’t seem to correspond to anything.
My gain[3] appears to be 1+gain saturation, whereas your gain[3] doesn’t seem to correspond to anything.
I haven’t been able to decipher lift[2] and gain[2].
Do you, or does anyone, have an explanation for this?
