Takes into account the position of the viewer. It models the reflection of the light source back to
Specular Reflection
the viewer. It can create the illusion of shininess. For realistic effects, you can animate this control by using higher
and higher values to mask the transition from filtered to nonfiltered versions of the layer.
Controls shininess. Very shiny surfaces produce small, tight reflections, while duller surfaces
Highlight Sharpness
spread the highlight out into a larger region. Specular highlights are the color of the incoming light. Because light is
typically white or off-white, broad highlights can desaturate an image by adding white to the surface color.
In general, use the following process to adjust lighting: Set Light Position and Diffuse Reflection to control the overall
light level and shading in a scene. Then adjust Specular Reflection and Highlight Sharpness to control the strength
and spread of highlights. Finally, adjust Ambient Light to fill in the shadows.
Card Dance effect
This effect creates the appearance of card choreography by dividing layers into numerous cards and then controlling
all geometric aspects of the cards by using a second layer. For example, Card Dance can simulate an extruded pin
sculpture, a crowd doing the wave, or letters floating on the surface of a pond.
This effect works with 8-bpc color.
Original (top left), and with rotation adjusted using Camera Position controls (bottom left) and Corner Pin controls (bottom right)
Original (left), gradient layer (center), and with Card Dance applied (right)
Apply Card Dance to the layer to use for the front of the cards. To set the view, use the rotation or perspective
controls, or match the perspective of the effect in any scene by corner-pinning.
