What is it with "silver rich" emulsions? It may have been an issue in
late 19th century glass plates, but it became much less important with
20th century films. The only 20th century film I am aware of that had
its shoulder near the upper limit of what you could print on paper was
Panatomic X that shouldered off near the top of Zone IX. Perhaps some
Pre-1950 films also did this.
But any film that can produce a density of about 2.0 has enough silver.
And since the introduction of T-grain films, they require even less
silver than ever before to provide sufficient covering power.
