Wondering generally if developing your own bw film and being very precise about controlling the variables is worth it if trying to use the zone system...

or is it your opinion that digital processing can do the contrast manipulation part of it easier if you just get "close enough" exposure and development

Second question: if you are going to shoot negative film, the traditional zone system says expose for the darkest area you want good detail (like zone iii) and then you develop for the highlights and contrast. But if you are scanning the negatives, the dense highlights are hard to pick up, so do you flip your approach and expose for the highlights or do you just try to be spot on (or err on the side of underexposure)?
