The principles are about the same for all reflective material. This example isn't the easiest to read, but it shows how similar preferred reproduction curves for color and B&W prints are.

And I'm sorry, the inverted graph matches almost perfectly with mine and the classic preferred curve. Highlight separation is sacrificed for the mid-tone contrast. The tones are lighter than the original scene. It's easiest to miss mistakes in graphs, charts, and with math when proof reading.
Does this look any better?
