[pure-silver] Re: Pre-Exposure of Negatives

Why do you think N- development is the better choice? That changes the
entire film characteristic curve. Pre-exposure, uniquely changes the toe
part of the curve alone, this way, maintaining mid-tone and highlight
contrast. N- development reduces overall film contrast.

That said, wouldn't a simple overexposure by a stop be the better choice.
For the deep shadows, it's the same as a Zone I pre-exposure, and the
highlights can be burned-in during the printing stage. It should also give
better shadow contrast than pre-exposure.

Has anybody ever made two negatives, one without and one with pre-exposure?
I'm sure they have. But has anybody ever tried, which made the better print,
using VC-papers and other darkroom techniques?
