filmscanners: Re: Coolscan IV; Nikon Scan 3

Please see my responses (in Bold if the formatting comes through) to the

The Coolscan IV has a USB interface.

No problem with focus so far.  I have been using fairly flat slides and
negatives - B&W and color.

Thanks. I'll try the "exposure" in Vuescan.

Nikon Scan has a choice between several gamma 2.2 and gamma 1.8 colorspaces.
2.2 Spaces:
Bruce RGB
NTSC (1953)
Adobe RGB (1968)
Wide Gamut RGB
Wide Gamut RGB (compensated)
Scanner RGB

1.8 Spaces:
Apple RGB
Color Match RGB
Apple RGB (compensated)

I am using the sRGB colorspace and it seems to work well - although I am new
to this.

Nikon Scan 3 also has a factor default CMYK or custom profile option.

A factory default or custom ICM profile can be set for the monitor.  I have
mine set for a Gateway VX700a ICM profile.
