I'll be the first to say that understanding some of this is difficult. For one thing, we all talk about scans as if we are scanning a pixel - or a bit of the image. However, they are just reads, as in a value from 1-255 in lightness darkness for three different channels of color separated light.
I do understand the stated resolution issue. It shows up clearly in the Tango, which can do 11,000 spi, yet only resolve 4000. However, you have often said that your assessment of the real resolution of the 750, for an example, was around 2000 or so (don't remember the exact #). I understand that this is quite different from pixel count, and is not the stated resolution of 5300 or whatever... However, if it is true that it is at a true optical of 2000, the 2400 you stated as the max one could get from a 4x5 would be very close.
What am I missing?
