Digital BW, The Print

I feel Austin about to pounce! All scanners scan in RGB mode and convert and
invert in the scanner s'ware. CCD scanners tend to have some channels of the
RGB more accurate than others , red blooms for instance and on some of my
scans has more noise in the shadows, by doing the conversion yourself you
can fine tune the conversion. You also have 'all the data' if you scan in
raw even if you scan as a 16bit greyscale and let the s'ware do the RGB
conversion. i agree with you about the RAM issue though. But before we know
where we are folk will be using AF cameras and inbuilt exposure meters if
you let the software do all the work...
