Adjust the following parameters.
Adjusting the Y balance
Setting the Y balance on allows you to specify that, even if the hue is the same,
only portions of a particular luminance will be replaced by the background.
For an overview of the Y balance, see “Y balance” (page 223).
1
In the Chroma Adjust menu, set [Y Balance] on.
2
Adjust the following parameters.
Adjusting the chroma key shadow
This function allows a shadow falling on the (typically blue) background color
to be rendered more realistically. Since portions of the (blue) background of
less than a certain luminance are treated as shadows, there is no effect on
cutting out of the foreground.
1
In the Chroma Adjust menu, set [Shadow] on.
2
Adjust the following parameters.
Notes
When chroma key shadow is on, key edge is changed to normal, and soft edge
is switched off.
