Blend Shape
determines the rate of
roll-off across the blend width, i.e.
how quickly the white levels
across the blend change from light
and dark. Increasing the Blend
Shape setting accelerates the rate
of change at both extremes so that
less of the region appears mid-
gray (see Figure 3. 32).
Decreasing the Blend Shape
setting slows the rate of change so
that more of the region appears
mid-gray. For most applications, this subtle control is best left close to 50.
Blend Midpoint
determines the white
level at the blend midpoint (the point
equidistant between the beginning
and end of the blend). Increasing the
Blend Midpoint setting creates a
blend that appears brighter than the
rest of the image. Decreasing the
Blend Midpoint setting creates a
blend that is darker than the rest of
the image. A setting of 50 means the
midpoint is approximately 50%
black—for best results in most
applications, keep fairly close to this
default.
Show Blending Overlap turns your
defined blend width area to solid
gray so that two adjacent images can
be seamlessly aligned simply by
overlapping their gray bars, if
needed. Toggle the Show Blending
Overlap off to reactivate the blend
effect.
Other Functions
For convenience, the Edge Blending
submenu also includes related options for
enabling a specific color and/or test pattern,
or for working with colors or the lamp. Such
functions duplicate those provided elsewhere
in the menu system.
