Mark,
The reason that the films have different shaped curves is becuase they were developed to provide different contrasts...may be you should read Grant Haist's book on "Modern Photographic Processing". It is a definitive treatese on photographic films and process chemistry. Dr. Haist was one of the top researchers at Eastman Kodak. Last time I bought a copy it was a mere $110, 25 years ago. If that's not sufficient how about try Mees and James, "The Theory of the Photographic Process". C. E. K. Mees was director of research at Kodak, and James was one of the most senior researchers along with Grant Haist. That's a fun one to read as well...silver imaging, contrast curves, effects of grain size on sensitivity hence contrast...boy does that bring back the days of wine and roses at R.I.T.

- films have different shaped curves Terry that's really not contrast.
Some call the middle part "gamma". And on and on.
