Digital Tutors - Multi-channel Compositing in Nuke

In this series of lessons we'll learn how to composite with the channels system inside The Foundry's compositing software, Nuke. We will start using a single multi-channel EXR file created in our 'Introduction to Channels in Nuke' course and finish with a composited render.
We'll begin this course by learning how we can use the Merge node with a multi-channel pipeline. We'll then learn how we can isolate nodes such as color correct to only work on a single channel. After we merge our basic passes, we'll do some basic color correcting and masking. At this point, we'll learn how to use the Backdrop and Dot nodes to organize our node tree. After that, we'll add in the final passes and composite our render on top of a photograph while keeping our shadow. We'll then make final tweaks to our image and add a light wrap, erode and grade node to make our two layers fit together better. This series of lessons will illustrate the basics of compositing a 3D render using the channel workflow inside of Nuke. For further information on creating and working with channels, check out our 'Introduction to Channels in Nuke' course.
