• Keylight: Extracts an unpremultiplied plate.
• Reorder: Places the alpha into the RGB.
• Bytes: Boosts it up to 16 bits—you are sure to get banding on the Blur+Emboss in
8 bits.
• Emboss: Extracts a sense of lighting direction. The elevation is set to 0.
• Blur2: If you do not blur the background, it makes her look transparent.
• IMult1: Blends the color into the “lit” areas. Note it is assumed that Blur2 has an alpha
of 1. If not, you must insert a Color–SetAlpha.
• Screen: You can also use an IAdd.
