The image is now grey although you can view the colour by switching the
preview check box. Now you can sample and modify the lightness and of the
six colour channels as you would in colour and interactively changes the
grey levels. An amazing amount of control.
Is this a known method of B/W conversion? Have others tied it?
Yes, I remember some famous photographer celebrity or another presenting a long winded discussion of this technique at one or another conference in the area a year or two ago. It works well, he just wasn't a particularly good presenter.
