A Book on General Image Editing Concepts?

halftrack asks: "Someone I know wanted 'Photoshop for Dummies' for Christmas because she wanted to learn how to use it properly (who hasn't struggled trying to draw a simple line?) However, having a strong disliking for any sort of vendor lock-in I went searching for a book that would teach image editing without tying it too strongly to Photoshop (or Gimp for that matter). However, all my searches turned out blank. Thus I was wondering if there exists such a book, or is the field too diverse? The ideal would be a (thick) book that would cover the basic concepts (layers, paths, selections, channels etc.,) before presenting how these concepts are implemented in different applications. Such a book should provide the reader with a portable skill-set and give her/him the ability to objectively choose the right tool for the job, at the right cost. Does this book exist?"

Darn, my mod points all left yesterday. This is exactly what I was going to say.
