Thanks, most illuminating.
In the 1960es Kodak published a paper on why an S curve was best. Less computation, but more labour intensive: shading and burning, waving hands in the light cone when enlarging plus suitable choice of exposure and development ,or decades later, similar imprecise and laborious work in photoshop.would achieve better brightness balance .
My generation was taught "Algol-60" and I have given up on anything except ready-to- run subroutines on W-10 or "deb" packages with all dependecies, so I am not optimistic about the possibility of compiling such code to run on my computers.
