To be fair Pan F+ does do as well as many of the others.
Falls off severely... At the red end they all do and most
at about 630 to 640nm. Delta 3200, IIRC, will make 680nm and Tech
Pan will make the lower 700s.
Now about that blue end. Ilford tests using 2800K tungsten light.
You will see that all their films drop severely some where around
400nm. That is not the case with Agfa and Kodak, both of which do
not specify the source of light for testing.
BTW, have you ever used a Macbeth Color chart to test film? Dan
