To me, knowing simply that a particular exposure on a particular negative was, say, 1/15 sec at f/22 is not, by iteself, all that informative. Unless of coarse, the negative is obviously grossly over or under exposed, then you can clearly see something went wrong. As a ZS practitioner with large format, the exposure that I give needs some context................noting the particular area of the subject that was used to make the shadow placement on which the exposure is based can be very helpful, as Ian alluded to above. My notes indicate the "placement" of the meter's EV reading of a given shadow area i.e., EV 12 placed on zone II, then from that the appropriate f/stop and shutter combination is easily decided. There may be reciprocity and/or bellows extension to factor into the exposure that is given. Later when looking at the negative it can become very informative when looking at that shadow area to determine either it's goodness or it's badness, so to speak. That's half of it..............it's not part of your OP, but the other half is to arrive at how the negative is to be developed based on the exposure placement you want to give.......that's probably another thread. But it suffices to say that recording exposure notes can be vital to understanding what went wrong and what went right, especially when some time has passed between the exposure and when you develop the negative, sometimes it's not right away.
