I misphrased the question. I thought Jones looked at going backward through the windmill but I guess that's just reverse engineering a given example. I just quickly wondered if one could start with a known paper characteristic curve, a desired set of reflection densities along the curve, and a known subject (meter readings), and somehow work out the hypothetical/theoretical negative required. I guess there are too many variables.
