I have one more question:
When doing BO, I typically edit my files in RGB and just before
printing, I convert to GS.
When using QTR, at what point do I convert to GS? Just before
printing. Earlier it was mentioned to edit the image in GS.
Also, if I plan to do toning with QTR, I presume I should be toning
the image in PS as well. Correct? But, won't the color (toning)
info get lost when I go to GS.
So toning is really handled by QTR and there really is no way to see
the image toned in PS when editing in GS.
Sorry if it sounds like I'm babbling.
