This summer I used a mixture of PL100, APX 100 and FP4+: My last 4x5 APX, my first 9x13 PL100, and FP4+ in 5x7".

I can see no difference in shadow density on these three films developed in Pyrocat-HD by inspection. I have no densitometer and have not tested "properly", just shot similar scenes with all films at the same exposure. I judge my shadows when trying to print the negatives...

PL100 also contracts very well in compensating developers, making it possible to get full details over a 19-stop range.
