I understand that part, and that's what I've been doing (I shoot a lot @ +.3,+.7, even +1, and sometimes, depending on the light and the scene, +1.3), and getting good results. But ... when I want a low key shot, with lots of dark areas in a photo, that's where my results suffer. Noise in the shadows is a constant problem for me, yet I don't see it as much in the work of other people. They seem to get cleaner shadows with better Zone 1-2-3 separation.
I sent you some examples of this a month or so back, but hadn't heard back from you - figured you were busy with other things (which you were) or maybe didn't get the message, then I got overwhelmed with some things here ... I want to be able to get better low-key results with less noise (quantization maybe?) in the darker areas of my photos on a more consistent basis.
