>>4364696Hm I didn't know that. Seems like these things are all upscaling. According to this guy even the plusteks only provide 50% of the claimed dpi. All things considered I still think flatbed scanning provides more than acceptable results and it's by far the cheapest and easiest, specially to create contact sheets of the whole negative.
Pic related is the screenshot of a 100% crop. The negative was scanned at 1200ppi with an old epson stylus SX235W.
