Brian,

It isn't a matter of 'adding density'. In a good pyro negative, the
densities consist of both silver and stain. In the shadows it's mostly
silver, in the highlights there's a lot of stain, and *less silver* than
in a negative developed in a regular MQ formula. This makes Pt/Pd, which
"sees" the stained highlights as really dense, print with adequate
contrast. At the same time a VC silver paper "sees" these dense
highlights as really soft because of the stain's color, and so prints
them with detail. A graded silver paper responds somewhere in the middle.---Carl
