Looking at the digitaltruth page cited by Ricardo above is educational in terms of Silvermax in SM vs Rodinal. But one thing that caught my eye is the general amount of detritus that we see on the images, for example, on the window screens and such. What are odd white spots, and the sort of fracturing that's visible? I've seen such before in some of my negatives and have wondered if I was seeing mild reticultation along with defective (i.e., not uniformly coated) emulsion. Is that the fundamental, basic structure of the film we're seeing there? I would have hoped for something much more uniform.
