Somewhere--I believe it is in the Kodak literature--I read a warning
before I first used Tech Pan to the effect that you shouldn't be put
off by the apparent thinness of the negs, that they will print far
punchier than they look.  And I remember seeing it again recently.

This, however, presumes use of Technidol, I suppose, and use of a
different developer could change results.

A post some months ago in this list quoted a source (magazine
article??) that had investigated the use of Tech Pan with sharp red
filtering for use as a near-IR material and concluded that by the time
you get adequate filtration you've cut the effective film speed back
so far as to cripple it for any practical use.
