Ho hum. You just reinforced my claim that D100 has an unswept curve favoring highlights. But you have to overexpose it rather badly to get it to shoulder off. Still, to gain as much of a usable semi-straight line as TMX100 has, you have to cut Delta's speed down to around 50 - a full extra stop more than TMX with its distinctly steeper toe.

Yes, Pan F develops quite fast. But in both cases, Pan F as well as D100, a staining pyro developer like PMK does distinctly help recover more highlight gradation when silver printing than a common developer like ID-11 or D76 would. And frankly, I don't care for boring. I like life and sparkle with any film I use. But the whole point is to choose the correct film for the anticipated scene, or at least something versatile enough to likely work well.
