I am not a ZS user as such but have a question that has intrigued me for a while.
Assuming z3 is the shadow reading to determine the exposure for the shot in front of you, which zone do you as an individual photographer assign as the highlight value?
The same scene with 3 and 7 will definitely produce a different negative compared to the same scene pegged at 3 and 8.
I'm looking at this to understand as where you would position your normal shadow and highlight with the ZS, and which value you use for the out limit.
Also if you are shooting a scene that has an obvious z3 but the highest value is say z6 how do you accurately determine a genuine highlight value?
