I picked that film because the density data was available, and it was the most consistent particulate size film available, and it was reputed to be the most consistent homogenous density mix of crystals within the sensitive film layer. My assumption was that the TMax100 crystalline molecule was the smallest discernible and quantifiable light capturing receptor. Therefore, the closest analogy to a digital sensor pixel. As I remember it, the particulate size, and therefore the effective pixel density, was around 15MP per square inch. The closest ( B+W only) comparison is the MM. The MM is about 10MP per square inch. Based upon this, and for all practical purposes, digital sensor technology resolution has caught up with chemical resolution. Too much time on your hands is a bad thing......you worry about things that are purely theoretical. This happened to me as well when I first retired. Seems a pattern....
