Figure 190. DPM – SpecFX– Shadow Crop
When
Use Image Crop
is selected, crop values of the shadow match the crop
values used for the primary image. Only shadow edge softness controls are
active in this mode.
When the
Crop Softness
data pad is selected soft knob controls for shadow
edge softness are available (
Top, Bottom, Left
, and
Right
). The total softness of
the drop shadow edges will be the softness of the shadow edge combined
with any softness of the primary image.
When
Use Shadow Crop
is selected, the edges of the drop shadow can be given
crop values different from the primary image.
Lighting Menu
The Lighting menu has four colored light sources, positional in 3D space
for each delegated keyer. Each light source can be a Point, Bar, or Plane. The
apparent reflection of the light source simulates the physics of incident
light falling on a surface, including specular effects and light falloff due to
distance and geometry. The lighting parameters interact with one another,
permitting the creation of subtle effects, and are key-frameable.
Some extremely low lighting values (particularly Light Softness) when
used in combination with other lighting values, can create visible artifacts
(stair-step aliasing). Due to the intricate lighting parameter interactions, if
these values were restricted to prevent all potential artifacts, other useful
