Using Edge Detection for Fine Selections

gimpbible-f1502This image corresponds to Figure 15-2 in the book. Using the edge detection filters in GIMP, you can quickly make fine-grained selections for detailed images like this kitten photograph. Listed below is the XCF file for the finished image in the book (note: there’s no need to decompress this file. GIMP can read .xcfbz2 files natively). In the XCF file are layers and channels for each of the steps described in the book. Photo credit for the original photograph goes to Tina Keller, who was kind enough to release the photo under a Creative Commons license.
