The Cyan to Red slider adjusts color on that axis, reducing Cyan, while increasing Red
in all colors in an image, with a positive adjustment, and increasing Cyan, while
reducing Red with a negative slider adjustment. Use this slider when you feel there is
a global color cast in all your images that is on the Cyan to Red axis.
The Magenta to Green slider adjusts color similarly along that axis, while the Yellow to
Blue slider work on a third axis. Each of these three axes is 120 degrees apart on the
color wheel. It is possible to adjust two of these sliders at a time, for color casts at
some angle between two of the sliders.
These sliders do not selectively adjust one color, they effect all colors in all images.
They are a quick and easy way to adjust global color casts, for cases where images
consistently seem a bit green, a bit cool, or a bit warm, for instance. It is very fast to
adjust the sliders and build a new profile, so making a series of adjustments, with
descriptive names, and then testing these new profiles, first in a print preview mode,
then in actual test prints, is a simple process.

Sliders
For images to be viewed under optimal lighting conditions, these sliders need not be
used. Full spectrum lighting in a color temperature range between 5000k and 6500k
(the general range of sunlight/daylight) is considered ideal. If your images are to be
displayed in a known location, and its lighting conditions are not optimal, use the
PreciseLight

sliders to compensate for these conditions.

Brightness Slider
This slider allows you to compensate for difficult viewing light conditions. If your
images are to be displayed in a dim environment, a profile compensating for this can
