Digital BW, The Print

Peter, as I understand it, in a stack of layers, each layer acts upon the
cumulative actions of the layers below it.  So two curves layers will act
differently than two data layers.

This is the same logic that dictates that when you want to use an adjustment
layer to modify the image (i.e. overall contrast, or gamma), you put it
below the VM layer, but if you want to modify the VM layer itself (in order
to tweak for linear response) you put the adjustment layer above the VM
layer.

Or maybe I've been sniffing too much Kami...

What if you used two adjustment layers (one nc and one mw) at the top of
a layer stack, with both set to 50% opacity?
