Alan, there are many methods for generating curves to redistribute
print tones. I learned on Dan Burkholder's instructions back a
ways, and many people have generated curves with similar trial and
error methods. . What I've gathered just from watching several
forums out of the corner of my eye is that QTR is widely considered
to give the best results of currently popular methods, though
difficult to learn (that's just my general impression). If you don't
want to get that geeky about it and just want a quick way to get
there, I highly recommend Michael Koch-Schulte's easy instructions,
using ChartThrob to generate the curve. It works great, very easy to
understand, and it's free. Here's the step-by-step instructions for
creating digitial negatives:
