Each filter effect can stack with previous filter effect, the combinations are endless, plus you can create your own "recipes"and save them for future reference. It might sound a little complicated, although it's very straightforward, especially when you have guide like this. There are a lot of new features in Nik Color Efex Pro that Odell explains in detail, like adding, combining and rearranging filter effects, and using Control Points for targeted adjustments. The Photographer's Guide to Color Efex Pro 4 is illustrated with screenshots and photographs so you know just what filter to reach for and how to use it. You can control how your image looks, from photorealistic to an edgy artistic look with each definition of the various filter effects.
