<EM>> Back to scanning - if you need to get all the info that is in a
|
|
</EM><BR>
|
|
<EM>> photograph ABOUT THE ORIGINAL SCENE, a three channel scanner is enough,
|
|
</EM><BR>
|
|
<EM>> because the original photo process has already reduced it to 3 chans.
|
|
</EM><BR>
|
|
<EM>> By using a multispectral scanner, you'll only get more info about the
|
|
</EM><BR>
|
|
<EM>> spectral shapes of the pigments (dyes) that make up the photo.
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<P>Assuming that the photo is perfect, yes.
|
|
<BR>
|
|
If you need to determine if something is red, or a reddish stain, then
|
|
<BR>
|
|
you can't do it solely by looking at RGB.
