Sean Bagshaw has once again created a valuable learning resource with the TK8 Video Guide. It contains 36 chapters, is 5½ hours long, and covers the TK8 plugin in detail. There are five chapters from the series below and a complete list of all chapters at the bottom of this page. The chapters cover everything from practical things, like installing the plugin and setting up the workspace, to creative applications like color grading, luminosity painting, and Orton effects. A 30-minute complete-workflow video is included to show how the TK8 plugin can be used from start to finish when processing images in Photoshop. I'm sure you'll find the series useful and will enjoy watching it as well.
