Firstly, thank you for this program - it really does make scanning simpler. However... :)
With my old scanner (CanonScan LiDE 20) both text and photo modes work very well. The shift to 2-bit greyscale works well and it does look better than the older 1-bit b/w.
With my new scanner (CanonScan LiDE 210) the combination of the settings, the hardware and the material I am scanning is currently too sensitive: it picks up too much light grey from the page. Altering brightness and contrast settings would be one cure, except that this is not currently an option in Simple Scan, so I have to do it in GIMP or similar.
Looking at the output files, the four level greyscale is currently '0% grey (i.e. white), 33% grey, 67% grey and 100% grey (i.e. black)'.
For what text mode is for, I think it would be better to scan in a higher (four bit?) resolution and to do some simple post-processing so that the greyscale becomes '0%, 50%, 75%, 100%' or even '0%, 60%, 80%, 100%' (i.e. concentrate the output resolution on on the darker bits).
