scan the crop with a higher resolution ? Sure. Depends on what sort of equipment you have. Some "desktop" film scanners do 4000ppi. 'course, can also make a conventional projection print, and scan it on a flatbed. Errors always increase! Errors due to original lens sharpness, motion, focus, film grain. Two-step process of scanning a print introduces more errors. Modern materials and lenses do pretty good, however, particularly for CRT output.
