cmiVFX is recording these days in London a series of videos about the craft of Color for Nuke™ compositors. A wide in-depth course on one of the most important and fascinating topics in the world of audio visual. Step by step we cover all stages of color manipulation from the theory of light to the practical application grading in Nuke™ making a bridge of knowledge between the image in your mind and the image in your monitor.
This class is for people already familiar with Nuke, so you must be able to, at least, basically run Nuke, know its interface and a minimum of compositing fundamentals. This video is not designed to teach basic Nuke principles, (Everyone knows there are too many of those already), but it ill teach the topics found no where else! (Until the other training companies watch it of course!)
