Generel information om alfamanipulation

Du kan finde mere information på de enkelte effekters sider:

  1. Kroma-key (for simple chroma-key-effekter)
  2. Farvevalg (for komplekse chroma-key-effekter)

Baggrundsmateriale om compositing

For noget baggrundsinformation (på engelsk) er Wikipediaartiklen alpha compositing nyttig. Se også Porter, Thomas; Tom Duff (1984). "Compositing Digital Images". Computer Graphics 18 (3): p253–259 1984 pdf
