There are many scanners that scan images into 16,32 or more gray levels .
(Some very reasonable)
Is it possible to use color filters / colored cellophane paper to
scan an image through Red, Green and Blue Filters and then combine
the RGB values to create a colored image ?
Since color scanners are far more expensive than gray-scale scanners,
it seems that good color images could be created for a fraction of
the cost.
(I think voyager did something like that to create the color images)

Anti-PC-People STOP NOW. DO NOT READ FURTHER.
Can we use a $175-(DFI-HS-3000)-like, cheap scanner (which I just
purchased), to do the above?
There would be some programming required in combining the RGB levels
to get a good scan. But with 32 levels of each R,G & B. I don't see
why we couldn't get near photographic quality color images, at a 
fraction of the cost of color scanners.
Any Help on the above would be appreciated ?
