I really don't understand what Dave meant by his explanation. In my
work with lith film the density range *was* the exposure range. I
don't see how it could be otherwise, assuming you don't have some
kind of very strange curve.

Well, if you really need a DR of 3.2 for PT/PD printing your working
method and/or chemistry is *very* different from mine. I am curious
why you need such a long DR. Any idea?

As for details, I used Liam Lawless' reversal method of development
with Freestyle APH film. I followed very closely the working
procedures what Liam recommended in the article that was published in
Post-Factory Photography so if you want details I recommend you get
a copy of that article and go from there. It is definitely possible
with this method to get an effective density range of over 3.0 as I
made a mistake several times and fell into that range when working
toward a lower DR for carbon printing.

If I were to make enlarged negatives from lith film again, which I
will not because I love the flexibility of digital enlarged
negatives, Liam's reversal method would definitely be what I would
recommend. The results I got from it were outstanding.
