....Then there is the factor that is contributed by edge effects which brings up the topic of macro vs micro contrast. If you design the film to have high micro-contrast, then the contrast of fine objects is higher. This film functions well for 35mm. Actually, most films have graded high micro-contrast, medium contrast wider images and lowest contrast for macro images. Thus the transition from 35mm to 4x5 for example, with one film, may give a different visual result in the same developer, but then again, under good conditions, the images should be identical for detail.
This should show up rather strongly in a sine wave MTF test, but I have never seen it.
