Digital BW, The Print

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?

Peter,

That would give the same kind of control over the final tone. I tried it
both ways and the eye dropper gives very similar readings on the same pixel
but not identical, must be a difference in the internal calculations. It
would be interesting to carry the two all the way through to a print.

I do like your approach better though, since it is easier to save what you
have done as layers in the unflattened file. It seems there are always a
dozen different ways to do something in Photoshop!

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...

Bill\ufffdthis sounds right to me. For instance, if I use a channel mixer to
neutralize an image, I put any additional curves for contrast or weight
beneath it.
