110 Chapter 3 Depth Compositing

This is one example of the node tree you could create for this solution:

The KeyMix1 node layers a copy of city_/jointfilesconvert/1578512/bg, which is masked with RotoShape2, over the

finished composite from ZCompose1. KeyMix has a mask input, like all other nodes, but

also has a unique input for the mask you want to combine with the other elements.

Adding Haze to the Entire Image

When you applied the Fade node, the result was a “fade-to-distance” effect. This works

for the balloons because there’s a background for them to fade into. Not true for the city

background; it will just fade to black because there’s nothing behind the city_/jointfilesconvert/1578512/bg image.

To create a simliar fading effect for the city horizon, you add a Compress node

combined with a DepthKey node, as shown below, to simulate haze:
