There have been a number of threads lately that deal with some minor aspect of the shape of the film curve and the influence this will have. Two different tones close together in the print or simply how the print is lit can have a greater influence than some slight bump in the curve. How the tones ultimately look is far from being solely based on the negative's characteristics. Why are these people limiting their focus to only one aspect of the process and appear to be unaware of how it fits in with the whole?
