unlike digital sensors that use Bayer interpolation, a scanner captures the RGB data for every pixel. single pass, three pass, whatever. you get the full monty. it doesn’t make much sense to degrade the data so it can be interpolated from a RAW file. instead the user can save the data as either a (8/16bit) JPEG, or (8/16bit) TIFF file. Vuescan let’s you save the scan data into a special kind of extendable TIFF called a DNG. the DNG wrapper lets the scan program separate the tonal data from the color data. using LR or PS one can then apply their own secret sauce. :)
