In the Node View, select the munch_pre node, click the Layer tab, then click the
Over node.
An Over node is added to the munch_pre node.
5
Connect the bg node to Background input (the second input) of the Over node.
6
Now, insert a Color–ContrastLum node between the munch_pre node and the Over
node, and set the ContrastLum value to .5.
If you zoom into the edges, a white edge appears around Munch. This unwanted fringe
is problem number one.
7
To replace the ContrastLum node, select it in the Node View and Control-click the
Color–Add node.
The ContrastLum node is replaced by an Add node.
8
In the Add parameters, boost the Color (red/green/blue) values to approximately .4.
Note: To adjust the color values, you can also press O (for Offset) and drag the pointer
to the right over the Add color control.
Although the Add node is only applied to the munch_pre node, the entire image is
brightened. A node affecting more of the image than it’s supposed to is problem
number two.
