UI is split in two to divide the functionalities of the two sides. To the
left, all of the sliders under the words “Input Vector” are controls to
deine the vector that you want to qualify or isolate. To the right, under
the words “Output Vector” all of the controls affect that selected vector.
Not all applications break it down into this nice, obvious division of
tasks, but they all work the same way. You need to figure out in your
application which are the “defining” tools and which are the “affecting”
or “controlling” tools. Once you understand that, everything will make
sense.
To understand what defining and moving the vector does, look at the
Reference image of the ChromaDuMonde chart at the upper-left (upper-
left corner of Figure 5.17 ) . This is the source image. Notice the green color
chips at the lower-left of the ChromaDuMonde chart. These are the colors
that fall within the area defined by the green vector that has been selected
for correction ( Figure 5.18 ) .
Looking at the vectorscope, you can see the location of the green color
chips on the vectorscope. The three selected color chips fall within the
area on the vectorscope defined by the green vector area on the Sym-
phony UI.
