scanners almost always advertise their max multi-sampled DPI on the moving axis as their "max DPI"
the DPI on the fixed axis is usually much lower, say 600 for document scanners
so even with multi-sampling, because the photosites are so large, you basically just get a smear down the moving axis
looked up the v850 just to make sure I wasn't being completely retarded, Epson says it has a 4800x9600dpi hardware resolution
they don't say which DPI in which direction, but since that can increase to 6400x9600 I assume it's 9600dpi across the sensor?
so maybe I'm technically wrong but then does it matter when the "6400 DPI" scan looks like picrel
now just to be clear, I'm not advocating camera scanning, but I would definitely choose it over flatbed scanning when concerned about quality (convenience/price is another story)
