Peter,
They are are actually in Photoshop. Image>Mode>Duotone>
This takes you to a Duotone Options box.
Then choose either Duotone, Tritone or Quadtone. Try Quadtone. Then
select "Load" and you will be taken to a choice of different file
folers containing a variety of curves. I would start with the
Grayscale curves.
Also checkout:
http://www.luminous-landscape.com/duotone.htm
For a nice tutorial on this.
There is also a chapter in Photoshop 5 & 5.5 Artistry by Barry Haynes
with his curve. I believe there is now a Photoshop 6 version but I
haven't seen it.
Hope that at least gives you a starting point but keep in mind that
color calibration of the monitor and monitor to printer is vital to
success in doing this.
Anyone else have a source for additional curves or some curves of
their own they would like to share?
