Lithium chloropalladate and AFO alone make a very soft print. Significantly
softer than pure palladium developed out. With some papers, addition of
dichromate can make a substantial contrast increase without becoming gritty,
even enough to print a negative developed for silver-gelatin. Without
dichromate, you'd want a negative with better than 2.0 density range, unless
you are specifically looking for a print with all values compressed into
middle grays.---Carl
