Excellent illustrations and examples,
Rezension bezieht sich auf: Grokking the GIMP (Taschenbuch)
Bunks has done a magnificent job of explaining the basics, with constant illustrations of his meaning, and a text that, while very understandable, was never condescending.
But what really made this book appeal to me was his very impressive and cogent explanation of colorspaces and excellent tutorial on the curves, levels, and threshold tools.
Without a clear understanding, these tools seem mere playthings. Pull the lines up and down in the curves tool, and you get a colorful solarized image. What fun. I used it once, and put it away. Bunks showed me how to use these tools to quickly, easily, and precisely perform color corrections.
He elucidates a clear series of steps for maximizing the image's use of the available color range, removing any resulting or preexisting color casts with remarkable precision, and enhance the visibilty and impact of foreground elements. I followed this procedure on a number of images I had scanned, and some that were stills captured through a video camera, and the before and after differences were remarkable, for about five minutes an image.
The whole book is a great reference, but to me, the chapters on colors and the curves tool were worth the price by themselves.
