There's a paragraph on page 489 that speaks to both Michael's question and Marks statement. It refers to a study by Jones and Nelson on the relationship between the negative and the print. "According to the findings, a strong correlation exists between the density range of the negative and the log exposure range of the optimum paper only if the variations in the density range are due to differences in development, level of camera exposure, or type of film. When the negative density range are due to differences in the luminance range for the scenes, the correlation is weak. In fact, when the film characteristic, camera exposure, and negative development are accurately controlled and held at what might be called the "normal" level, there is a distinct tendency for observers to prefer prints made on the "normal" grade of paper (such as Grade 2), regardless of the luminance range of the scene. Although this tendency may seem odd, it appears to be confirmed by the common practice of photofinishing stations, where accurate control of the processing of films having uniform contrast characteristics has been found to allow the use of a constant grade of paper."
