I did not do that. The scans were made for 300 ppi x 13 in x 19 in Plenty high enough to get to the grain structure of the film. I specifically compared 160 through 640 ISO negs to sensor images. Same lens, same subject, same light. The drum scan of 160 film provides sharp grain structure which becomes evident in magnification before pixels become evident at similar magnification. Aesthetically some may prefer the film look. But from a purely technical perspective the digital image appears as a much slower (or larger) grain-less scanned film than the equivalent 160 through 640 35 mm film. I did not compare 30x40 prints. I compared on screen and 11x14 prints.
