In this segment, I construct a pass filter, commonly called a high-gain or band-pass filter. To do this, I use the HSV channels to identify what to do, the RGB curve to make an inversion mask, or negative, so that the image is added to itself, thus evening out the contrast and making a very flat image. This image can then be tiled and used as a seamless texture. I also discuss adjusting the final output for brightness and contrast, using the Blur node to smooth the contrast and make it change gradually across the image.

The Node Window is a workspace or desktop for compositing. In this video I cover all the mouse and hot keys you use for navigating around and in that workspace. I cover how to add/delete/move nodes, pan/zoom/autozoom the window.
Handy tip: Select a viewer node (or the composite output node) then press L to select linked nodes. This will show you all the nodes in the noodle that contributed to the image output.
