7. Often, the color values you set for the Low and High Clip values aren??™t enough.
So, hike the High Clip Color values to R:195 G:235 B:255 in the Compositing tab
of the Effects panel. Reduce the Low Clip Color values to R:110 G:150 B:220.
8. After you??™ve set the new clip colors, press F9 again. You??™ll see that the moon is
clearly visible, but the area behind it is black. So, in the Compositing tab, set the
Background Image to the Fountain.jpg as well. Then, render again by pressing F9.
Figure 16.21 shows the moon now rising up from behind the buildings.
Figure 16.21 With a slight change in the High Clip Color, the moon now appears to be rising
out from behind the buildings.
This is a good technique to use when your foreground image can support it. The example
here can use a little tweaking in the High Clip Color area, which you can experiment
with on your own. The less variation between the High and Low Clip colors, the better.
And, the less area to be keyed out, the better.While this is not the best keying method you
could choose, it is a quick way to consolidate operations and software, while maximizing
time.
