I can't find much info on how they actually function.
Main questions:
1) Is the film held right up to a CCD or CMOS sensor and backlit? Or is the image projected through optics?+
2) How scratch resistant is the surface of the film? Is it damaged by contact with the device?
3) What about the liquids used for wet scanning? Why don't they just use distilled water? And why does a layer of water between the film and the sensor
4) I know some scanners have a Bayer grid sensor, but some don't. Is that just drum scanners? (according to Ken Rockwell they use some kind of laser tech http://www.kenrockwell.com/tech/scantek.htm)
Are there scanners that use 3 rows of pixels (RGB) and slide the film along past the row, similar to a flatbed scanner?
