There are also many occasions when dodging/burning are required to produce a print that conveys a range/ratio of tones. Imogen Cunningham apparently kept 'maps' of her very involved burns/dodges. Something tells me that she wasn't compensating for bad lighting/processing.
Hexavalent, I do understand what you mean. However, it seems to me strange that someone would want to do this, perhaps analogous to someone taking an image off the internet and then manipulating it into something different, rather like music sampling and mixing. I guess it has its place, but a complete anathema to me.
