Hmm. My calculator spreadsheet says that a 24x35mm frame scanned
at 2438ppi nets an image 2304x3455 pixels in size, or 7.6
Mpixel. Something's off by a little bit somewhere... ;-)

RAW is really the name of a format type, a "RAW file" means a
different thing for every device that can create it. Viewscan
simply encode the metadata and sensor data into a very simple
TIFF format. If you analyze a Pentax .PEF file, it also is
essentially a TIFF file with embedded metadata, a couple of JPEG
low rez renders, and the sensor data in a tagged structure.
