3 In the Node View, select the saint_fg node and apply a Key–Keylight node.
4 Connect the saint_bg node to the second input (background) of the Keylight1 node.

of the car. This is a good place to scrub because there are no reflections (like the side
window).
The lesson images are logarithmic (that is, filmic, rather than linear digital or video)
color-space images. Don’t fret—you can specify the color space the node is working in
in the Keylight1 Parameters tab.
6 Set colourspace mode to “log” for this composite.
Note: All masking data is dependent on your monitor gamma. Use the viewer lookup
table to ensure you have an accurate key as you proceed with the tutorial.
