For those of you who haven't seen this before, it's from the original pioneers of Bryce. Or at least from the same company. This is KPT Equalizer, a filter you can use inside of Bryce (Terrain Editor, anyway) or in Photoshop/PSP. It basically allows you to determine a blur rate between different pixel depths, all at once. Similar to running a gaussian blur filter, for example, but on multiple distances with different amplitudes. Also are the contrast & bounded sharpeners, but we'll get into that later. In short, it's a simply amazing and dynamic filter for cleaning up color and contrast in an image...
