the video shows some other things but it should be straight forward once you are in the custom color space editor.
I'm a little confused as to the logic if what someone is trying to do is create a custom white point using your's or Dwayne's alternate white points. The video seems to be aimed at trying to match multiple displays/projectors by reading and recording the behavior of one so that you can match the others to it.
I wrote the following procedure to explain how I'm setting up alternate white points within Calman and would like to know if it should work using this procedure. It seems to work but that's not to say that out of some dumb luck it does but can't be counted on working every time.
1) Select gear icon in upper right.
2) From the dropdown menu, select which color space you wish to copy and then select "New/Edit"
3) Next window, select "Advanced"
4) Select "Copy Colorspace". in this example, I copied D65, HD BT.709.
5) In "colorspace name" enter your description. In this example, I entered Tyler's 2017 LG OLED white point.
6) Leave "reference white to "Custom"
7) On the line that starts with "white" enter the "x" and "y" values that you wish to use for the new white point.
8) Exit this window by selecting "close"
1) to use this white point, under "gear" icon, "workflow basic options", "target Options, "colorspace target", select the new white point from the drop down menu.
My second question is what do we do about metameric failure when it comes to color coordinates? Do we have to have a perceptual match similar to what was done with white or is there a way to do it mathematically? Seems that the major part of the shift in LG OLEDs white point is we perceive it as having less blue. Shouldn't at the least Blue and colors affected by blue (magenta, cyan, yellow) also have alternate targets?
