These images each show a (nearly) full frame scan from a 35mm color negative, and a small section at the full 4000ppi scanner resolution. This is not a real scientific test; even though each image is exposed correctly, the relative sky brightness and the color is different in each scene. I'd not want to use these to make any hard comparison between film types. The next part of the story will come if I can scrounge a microscope at work. If I can put optical magnification before the digitization, I should be able to see what the un-aliased grain structure looks like. [I tried using one of those little Intel plastic "play" scopes, but the light source wasn't bright enough. Maybe I can cobble something together.]
