Each curve control box is square. The default, neutral position of a curve is a diagonal line that runs
from the black point of the image at the lower-left corner, to the white point of the image at the upper
right corner.
The horizontal axis represents the range of image tonality in the original image, while the vertical axis
represents the range of alteration you can make. By adding control points to the surface of the curve
and raising or lowering different areas, you are actually remapping the horizontal “input” tonality of a
color channel to an “output” value of your choosing.
Tip: The background grid makes it easy to see which parts of any curve are at or near the diagonal
default that represents no change made.
Ganging and Unganging Custom Curves
By default, the Custom curves are ganged, meaning that changes made to one curve are automatically
made to all the other curves.
Controls attached to each Custom curve; the handle on the upper-right hand side is the
YSFX vertical slider, and the slider underneath is the Curve Mix slider
