164 Chapter 5 Using Keylight
Using Keylight to Pull a Key
The first section of this tutorial demonstrates the basic steps for using the Keylight
node.
To pull the key on the “merlin image:
1 Add an Image–FileIn node, then browse to $HOME/nreal/Tutorial_Media/Tutorial_05/
images.
2 Read in the merlin_fg.jpg and merlin_/jointfilesconvert/1578512/bg.jpg images.
Note: To read in both files simultaneously, drag in the File Browser window to select
both files, then click OK.
You are correct: Thats not Merlin.
3 In the Node View, select the merlin_fg node, then add a Key–Keylight node.
4 Connect the merlin_/jointfilesconvert/1578512/bg node to the second input (the background input) on the
Keylight node.
Keylight has several color controls. In this lesson, the important one is screenColour.
