Re: filmscanners: Silverfast/ setting output size?


Thanks so very much.  I was vaguely familiar with what you said, but, never
has it been stated so clearly.  In the past, I'd used Photo Cds, then
Nikon's LS400, which enables one to set an output size in inches.  I've been
doing it all wrong, checking the "Resample" box in Photoshop immediately
after opening an image. I don't think it was all that harmful as I usually
print at the same size.  But, from now on, Ill know how to properly open an
image.  One further question.  Do you sharpen the image when doing the scan
or wait to use "Unsharp Mask" at the end when you are ready to make a
specific size print?
