If you have a continuous tone red-light-safe sheet film available at a
reasonable price, I'd say get a freezer full. They've just about vanished
over here. How big is it? Can we get some?
We used to be able to get Agfa N-31 P up to quite large sizes, and a very
nice film it is, price also reasonable; still available from only one
source in States (that I know of ) -- Palladio -- and officially, as far
as US office of Agfa is concerned, DISCONTINUED (the computer did it).
If your film really changes contrast with color filtering (does it say
that on data sheet or could this be simply effect of more or less exposure?)
get two freezers full......
