Methods were investigated and modeled to produce a graininess by density sample matrix. The graininess values were based on a model derived for certain imaging processes that has a high correlation to the subjective impression of graininess for nominally uniform image areas. After modeling several processes, a photographic technique was chosen and a matrix manufactured.
