Chapter 3 Depth Compositing 107
Fading With Distance
In this section, you’ll add some depth cueing by varying the color correction between
the foreground and background elements. There are many ways to do this. One way is
to pull a depth-based key from the balloons image and use it as a mask for a color-
correction node. Again, there are many options for the type of color correction.
In this example, use Fade node with the DepthKey node to allow the background to
show through as distance increases, creating the illusion that some of the balloons are
actually behind the clouds on the horizon.
To add a fade effect:
1 In the Node View, select the ContrastLum1 node, then insert a Color–Fade node.
2 In the Fade1 parameters, set the value slider to 0.3.
This fades all the balloons equally. Next, add a mask to vary the effect according to
depth (or distance).
3 Select the balloons node.
4 In the Key tab, Shift-click the DepthKey command.
A new branch is created with the DepthKey1 node.
