•
determines how much area is used for blending along an overlapping
Blend Width
edge. Slide bar values represent the number of eight-pixel steps used for the
blend. For example, a setting of "eight" creates a blended edge 24 pixels wide. A
setting of "0" signifies no blending. For best results in most applications, use a
blend width of 16-48 steps (128-384 pixels).
Ranges: 0-80 horizontal, 0-60 vertical.
•
determines the rate of
Blend Shape
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 3.19).
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.
•
determines the white
Blend Midpoint
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.
