Title: RedbrushAlpha Author: Pieter S. van der Meulen Description: The original image comes from a slide I took in 1991 and was scanned to PhotoCD. The alpha channel was created by taking the red and green channels. A photo-fill program (with varying simi- larity and soft-edges settings) was used to make the background fully transparent and the center of the plant fully opaque.
