Just brushing up on my zone system theory before going out tomorrow - it's been a while! I haven't shot black and white for some time and I decided to study the zone system seriously before shooting it again. My question is this: Assuming my first frame requires N-2 development and the second frame is very low contrast - let's say a two stop brightness range (S-ZIV, H-ZVI) - will the N-2 development effect the highlights in this frame just as much? Would the ZVI highlights be contracted to the same tonality as the shadows (ZIV) resulting in a completely flat, unprintable negative? With a three stop brightness range, I can compensate with the exposure by placing the shadows a zone higher, then increasing contrast at the printing stage, but with a scene of two stops, I'm not sure if the N-2 development would make the negative unworkable in terms of contrast adjustments.
