You'll get more done that way, not to mention the feeling of having really accomplished something each day. In this tutorial I'm going to show you the tricks you can play with noise. The Gimp is often thought of as a tool whose end product is a goal in itself. But Hollywood knows better. There, the Gimp is used as just another tool in a long list of tools to generate the final product - a special effects shot for a movie.
Noise plays an interesting part in that pipeline of tools.
Much of the 3D work you see in movies is done using 3D modellers and renderers, but the textures for those models are often done in 2D paint programs like the Gimp. For example, we can very quickly create reptilian skin using the Gimp, a little blurred noise and some color blends. In the following examples it is assumed that you will be using Gimp 1.2, even though technically it hasn't been released. It's pretty stable these days, and even if it isn't out yet, it will be soon. Reptilian skin I haven't studied reptiles to any great length.
