PE, fair points, but I think it can still be helpful to have a ZS framework. What about subjects with wider than normal luminance ranges? Not really a problem for most current films unless we're dealing with an extreme contrast subject, but there are decisions to be made. Also the ISO standard pretty much assumes you are using at least part of the film toe. And the paper has a relatively short straight line (from a reflection density perspective) in comparison to the film. What is correct film development? Etc.
I know I'm being a little argumentative here. Apologies for that. I don't believe in print zones, but still like the ZS inspite of everything I've learnt about exposure, speed methods, tone reproduction etc so far (much of it thanks to Stephen).
Perhaps the most important thing is to understand what one is doing, and know the variables and limitations. That has been the most valuable learning outcome for me when it comes to this stuff. I still use the Zone System, but I have a better grasp of what is actually going on when it comes to film speed vs a Zone System EI, the transitions from subject to negative to print, etc.
