Working in Lab Mode Space

| Lab mode seems to offer an number of advantages over working in RGB and CMYK
at certain times. What color space works best when going from a digitized
scan into Lab mode? I thought maybe it would have it's own working or colour
space on my scanner software but there's no sign of it in the driver (not in
Epson Scan or Vuescan). Do I ALWAYS have to convert into Lab mode from
another working space? Thx.

Of course you do. Your scanner's native output is RGB data - that is what it
measures. If you want anything else, you have to convert.

Whatever your scanner's color space is. If none is specified, try assigning
sRGB and see if you like the color saturation.

Vuescan can be configured to embed the sRGB profile. Later you may want to
calibrate more accurately, though IMHO this is not really necessary.
Vuescan will calubrate your scanner for you, using a 40 dollar IT8 target
($40 from Wolf Faust).

Yes, although if you are using Windows, the Curvemeister plugin allows you
to do curves in Lab without actually changing the format of your image.
This is a time saver, but the end result is the same as if you did your
conversion manually.
