Its a matter of density. Pictoria is supposed to be able to hold more ink
without running - so it should be able to create a higher contrast
negative than other transparency mediums.
If the negatives made with a regular transparency work for what is being
done fine, if more contrast is needed pictoria. If even more is needed
then perhaps waxed paper.
I do my cyanotypes by shooting ortho film in camera and developing in a
low contrast developer. I make big negatives and contact print them.
This works very well, and is fairly simple, now that I have a reasonably
good developer.
