This is quite evident if you ever make positives (slides/dias) from
technical pan 2415. The clear parts (highlights) are much better than
those made from other b/w films.
And yet, TP does not suffer from halation. Why, then do other filmd need
to be so much more opaque? Frankly, why cant other films be as good as
TP?
