I often read of slide films having so many stops of latitude. But it seems to me that a third of a stop makes a big difference when figuring the exposure to use. What does Mr. Goldfarb mean when he refers to "4-5 stops"? Can a slide film rated at EI 100, such as Provia, be used successfully at EI 3200? Or does he mean that when properly exposed the film can register detail in a range of 4 to 5 stops from shadow to highlight?
