Five Interesting GIMP Filters
The Gimp is a powerful graphical application that can handle just about any kind of bit-mapped editing job. You can re-touch photos, shrink or enlarge pictures, combine elements using layers, and many other operations with little to moderate effort.
The program also has a bunch of interesting “filters” that transform your picture into something new. Perhaps you need to make a cool text logo for your company or are a teacher needing to create some coloring projects, for your kids. The Gimp has you covered in those departments. And, once you try using a few of the filters, I'm sure you'll see opportunities to "filter" pictures, all over the place.
The emboss filter creates an etched rock picture transformation. Figure 1 shows one of the local buildings in my city. Does anybody recognize the building and location? It's near a famous vacation spot. The picture was taken with a Nikon D80 DSLR camera using an 18-200 mm VR zoom lens and is a 3.2 MB JPEG image. Figure 2 shows the building after running the "emboss" filter.
