I have been thinking about the Zone System and its goal of maximising image quality given the limitations of film sensitivity and the necessity to choose specific developing parameters.
Clearly you can't extract information that was never recorded or was burnt out but given that raw images can be tweaked in post processing, how critical is it get things exactly right at the outset? Does for example +/- 1 stop exposure compensation have any value beyond the quality of a jpeg (if you shoot raw+jpeg)?
Perhaps what I am asking is how much latitude do I have with post processing raw images? (Nikon D90 and P7100). I have zero experience with raw so far (in case you hadn't guessed).
