Shannon,
Don't forget about selenium intensification if your negative isn't up
to contrast. It works great and usually gives effective +1 contrast increase.
Mix it 1 part selenium toner to 2 parts hypo clear working strength. Tone for
up to 5 minutes...beyond that no extra contrast will be produced.
