I was trying to get to the point that the dye clouds in the two films mentioned are similar in size and as dye clouds are not sharp edged as say TMZ in Rodinal would be. The scanner was treating two similar films differently. My real point was that I think Mr Ford's difficulties lay within the programming of his scanner and not aliasing. Perhaps I'm misinformed but grain aliasing is when the light dark pattern of the grain coincides with the spacing of the CCD's so that small clumps are seen as much larger clumps. I think it would be a good learning experience if those on this list with more experience in the scanning business were to discuss at greater length differences in grain size and shape or dye cloud shape to the scanning process. Many people will continue to shoot film and then scan, so this is possibly very important information. Likewise, it may explain why individuals report such widely divergent results for different films: different scanner designs produce different results on a film by film basis. If CCD technology renders sharp or softened silver halide differently then different developers might be chosen. Likewise, some films with silver halide spacing "just right" might scan more smoothly than others for a given CCD array or whatever is used for the sensor.
