Chroma Key Setup Menu — Shadow Adjustments
• Use the Shadow Clip knob to adjust the shadow’s threshold.
• Use the Shadow Gain knob to adjust the gain (softness) of the shadow.
• Use the Transparency knob to adjust the shadow’s transparency.
Note
The default values for Suppress Gain and Suppress Luma should
be appropriate for the best possible chroma suppression in almost all
cases. It is
not recommended that you adjust these two knobs for the
majority of chroma keying instances. Use Suppress Clip only to
select the desired hue rejection.
Operating
Tip
The Shadow adjustments allow you to extract a shadow from the
chroma key source itself — typically, the actor’s actual shadow that is
cast on the blue or green screen.
Note
If there are flaws and blemishes in the chroma key set’s background,
they will
also appear as shadows. Normally, a superb set with careful
lighting is required for natural chroma key shadows.
