If two papers are identical in all ways but dmax, the paper with the lower dmax is necessarily shorter in latitude and will reproduce a shorter tone scale.

I think that you can see the logic in that. You can demonatrate that for yourself by taking a paper curve from the Kodak web site and altering it to show the two curves.

Without such curves, I guess this is about all I can do in the way of explanation. I hope it helps.

There are other curves possible, but this is the simplest case. I hope it helps you.

Use what works for you or what you like best though.
