Sorry to reopen an old thread, but it seems to fit here.
I'm working towards making my process a lot more systematic to save on flailiing around with exposure and grade. I want to build up a table of exposure time multiplication factors against colour head filtration settings so I can move between grades easily without having to test strip at each grade. I've been trying to keep midtones constant but i'm finding it just too hard to be consistent.
Most people seem to set the exposure for highlights first, and then modify shadow with contrast grade so figure I would do this too. But just for the sake of better understanding, why would you for instance not set your shadow exposure first, and modify highlights with contrast grade instead? These two approaches would give me different numbers would they not? Would both approaches work?
Or am I missing something?
