Mark it is not exposure scale envy, but image recovery. I print not only for
myself but make prints for other people. Believe it or not, not everyone
uses the Zone system, pre visualization or any other method to predict an
out come and yet they still want to make a platinum print from the shoot. In
order to get everything, I sometimes find my self stretching backwards and

If I can do it, then when I need to do it it is not such a reach.


I normally use a mix of 50/50 which produces a steeper curve than the one

Eric, you described a PT/PD mix you use that has an exposure scale of about
Log 3.0. Do you use this mix for in camera negatives or digital negatives
or both?

I am assuming you use this long exposure scale (very low contrast mix) for a
reason-could I ask what that is? Or perhaps there is more than one reason?

Also, is this based on how you like to shoot/develop your negatives or is it
based on using a mix that you like the print characteristics of, so you
fashion your in camera negatives accordingly.

I'm also assuming you are not using this mix because of Exposure Scale Envy.

Best Wishes,

Well, that wasn't so hard. When I go to the unblinking eye site where you
show your pt/pd test, I see dmax at step 7 and and dmin and step 18 ,
showing 12 steps with an ES of 1.8. Step 1,2,3 were all of the same
density? And paper white is at step 19?

If, so that is not where I am counting. Steps 1 and 2 still show separation
and step 21 is darker paper white in my ES.
