Re: [Digital BW] best scanner for b&w

I agree with your post, although I tend to use the LAB mode and select to use only the lightness channel.  On an off topic issue, could you email me at simon@sclamb and tell me if you find your 3200 scans to be soft.

Thanks.

  I get better results with 48bit RGB scanning, picking only one of the three
  channels, for the following two reasons:

  1) Channel noise.
  2) Channel disalignment.

  Typically, although both issues are obviously scanner dependent, one of the
  channels is the best in the noise department, and the three channels are not
  perfectly aligned. Using *any* channel mix will therefore degrade the final
  image, unless you only pick a single channel (i.e. a 100% 0% 0% mix).
  I repeat that you should verify how much your own scanner suffers from these
  problems, but they are visible in both my Canon FS4000 and Epson 3200.
