Re: Lithium palladium vs. normal palladium



I think Sandy's saying:

"This is true when printing in-camera negatives, but it is not necessarily correct when working with digiyal negatives..."

I second this (As someone who had hard time to explain the same concept last weekend - to someone coming from contact printing silver-gelatine.)

With digital negatives, indeed you can squeeze more black from your paper without blocking shadows (full detail) and/or loosing delicate and rich highlights.

Quoting sanking@CLEMSON.EDU:

This is true when printing digial negatives, but it is not necessarily
correct when working with digital negatives. If one is working with a very
precise system of making digital negative it is possible to use virtually
all of the maximum density of the process by adjusting the curve. Working
with Mark Nelson´s PDN system I have found it very easy to use up to
98%-99% of Dmax and still retain excellent shadow separation.

Please let me begin by indicating that the maximum black density
possible from the materials should not be utilized in the print. The
actual maximum black in a print (and this is likely so for any process)
is less dense than the capability of the materials. This can be
demonstrated printing from a calibrated step wedge. If the darkest tone
is printed to maximum possible density, visual discrimination will be
lost between the other dark steps. Attempting to correct this in the
negative will likely lead to overexposure, hindering the highlight
values. Just as film ‘works’ within a certain range, so too the print
materials have their range.> --
