Kodak has three products for a niche business that do the same thing differently. Whether one emulsion prints well on the Gold channel or the Portra channel or on B&W paper is not a difference in the real world. First, how many people who have a darkroom are going to process their B&W film in C-41 then print it at home. Now I will agree that a film on the Portra line in a pro lab that prints exactly the same speeds things up. But why not let the amateur labs use this film. Portra prints fine in an amateur lab.
