[filmscanners] RE: Monitor calibration offer, kind of OT

["Paul D. DeRocco" <pderocco@ix.netcom.com>]

The profiles that come with monitors are only good for one thing: they have
the correct primary colors in them. Other than that, they're useless,
because they have no way of knowing how you've set the brightness, contrast
or color temperature. At the very least, you should use Adobe Gamma or
Colorific, using the monitor profile as a starting point. They help you
adjust the black level, set the white point, and measure the gamma, which
when combined with the primary colors from the original profile produce an
okay final profile.

In my view, the weakest aspect of these poor-man's calibration tools is that
they don't set the black level very accurately. Having a real colorimeter
gets the low end of the scale much more accurate.
