Hey Folks
So I took the dropper and made a selection over a subject to adjust skin-tone, did some adjustments. Then I decided the selection was not accurate so I reset the HSL selection I had done. I can still see the changes by toggling the node using CTLR-D. Why does reset not undo the changes to the qualified selection? The selection is gone but the color changes remain - that is a bit counter-intuitive.

Also I am able to make selections in both HSL and LUM in the same node with slightly different accuracy for each qualifier mode - which one wins? Or is it the maximum area covered by both?

You are making a grade to the whole image, but restricted to the area you qualified, or applied a window to, or both. Removing the qualifier should not and it does not remove the grade.

The HSL keyer uses all the parameters of H, S and L.. if you sue just a portion of those by selection it uses what you select.

Hi,
So I am trying to understand what you just explained - So I qualified the face and arms of the subject and graded it - this change only applied to the selection and not the whole image. Now when I reset the qualifier/selection - my common-sense understanding was that the selection and all changes made to it should get undone. My thinking in loosely in terms of object-hierarchy - the grade (the specific RGB value attributes) is owned by or only associated with the qualified selection so therefore when the selection is destroyed the grade owned by it or associated with it should also automatically get destroyed.

Are you saying there is no such relationship?

The selection and the changes are separate steps. Why would you expect resetting one to affect the other?

You'd likely be very upset in the reverse scenario. You spend precious time getting the qualification just right, but aren't too happy with the grade so you reset that to start over, and all of a sudden your carefully set up qualification is now gone as well.

Holy cow, that'd be a bad design!
