Re: Digital cameras as "scanners"

[byard pidgeon <bluedove@xxxxxxxxxxxx>]

Consider that a film scanner gives much higher resolution than a 5 megapixel
camera...mine gives 3175 ppi, yielding a roughly 30 megabyte file at 8
bits/color.
Scanner can also be used at 12 bits/color, which I doubt is possible with
the camera.
Also, by using auxiliary lenses, you'll be degrading the image.

Some early digicams were also scanners...Leaf and Agfa had these...but the
cameras were not meant for use as hand cameras, but studio tripod mounted.

So, my opinion is that sure, you can do it, but with inferior results.
