Message to Mark and Terry
To Mark. Terry does not use curves. He just inverts the positive.
Which means you are wasting your time trying to get him to take the
bait and fall into a trap. He is already in the trap, but apparently
oblivious to it.
To Terry. Terry, if you print a 21 step continuous tone transmission
wedge of density range of log 3.0 with pure palladium, and measure
the steps with a transmission densitometer, you will find that there
is some measurable difference in density between every single one of
the steps Normal wet processing would not allow you to use more than
about log 2.2 or 2.4 of the scale. However, the curve of good digital
negative systems such as PDN allows you to use every single one of
these steps.
