Hi, I am working my way through the tutorials on the Blog site.
les@les-N56VZ ~ $ photoflow --version
this is photoflow 0.2.8
I am trying to follow along with Black and white conversion in Photoflow from Friday, November 28, 2014,
When I create a new desaturate layer, all the methods from the selection picker work, except the Lab L channel, as per this screenshot.
