DR108 – Working with ACES

There are many advanced node trees that can make getting to the look an easier process, first let’s look at what a Node really is. With every serial or parallel node you add these are ‘corrector’ nodes, they perform primary or secondary correction depending on whether you use a qualifier/window/matte. Because of this nodes have two inputs, and two outputs that let you separately manage rgb channels, and the key channel which defines the isolated area of image processing or transparency for compositing. If you have created a really advanced node tree you would like to copy nodes from throughout the grading process you can add this clip to your Gallery, and Display the Node to drag and nodes you want to apply to your current clip, or Append the Nodes to your current selected clip. Serial Nodes are pretty straight forward, and is a linear approach to modifying your image. This could involve a first node that is your Log adjustment, a second layer that uses a qualifier to select someones face, and the last node to provide a dramatic colour look. It’s important to have you qualifier’s before this look node, as it will change the overall image hue, and throw your keys out of whack. If your going to be applying multiple effects and you don’t want them to interfere with one another you can use a Parallel Node, which stacks the secondary nodes and takes the same input RGB and is not limited to the amount of parallel outputs coming back into the Parallel mixer. The Layer node is good if you want to add hierarchy of layers as the latest will take priority in the mixing order, you can use the layer mixer node to define the blending type that merges the two layers back together.
