Right. Given its sensitivity to one end of the spectrum, it's hard to
see how you'll develop any shadow detail at the other end where there's
little or no exposure at all.

Slobo:

If you've already processed it in a litho type, Kodalith) developer then
you're probably out of luck as these are extremely high contrast
film/developer combinations.

If you've not yet processed, then develop it under inspection, (red
light) in 1:1 or 1:2 Dektol.  The results will still not be panchromatic
but rather contrasty orthochromatice... red items will appear very dark
to black when printed.

If anything can be done with PS to un-ortho it, then I'll be pleasantly
surprised.
