One would be a Formazo print and the other would be a standard print, both run through the same developer with one of your negatives and a step wedge. So, there would be 2 prints.
The Formazo comes in Soft and Hard (about 2 and 3 grade with Azo speed).
The choice of negative would depend on which batch they have left. If they only have the Soft, then you would need a harder negative, etc....
Does this make sense to you?
