Getting Started with Nuke - Nuke 101: Professional Compositing and Visual Effects - page 19

You will learn about editing properties in Chapter 2 .
The Viewer
Another important part of the Nuke user interface is the Viewer. Without it, you will be
lost as far as compositing goes. The Viewer is used to view your work as you go, receive
feedback when editing nodes, compare different images, and manipulate properties onthe
image. You will explore each of these as you work through this topic.
Notice that aside from the Read 1nodeyoucreated there'salsoanothernodeinyourNode
Graph,called Viewer1.Also notice that your Viewer paneliscalledViewer1.Every View-
er node represents an open Viewer panel. To view an image in Nuke, you simply connect
the Viewer node's input to the output of the node you want to view. It will then appear in
the Viewer panel itself.
You can connect any node to a Viewer node in two ways.
• You can click the Viewer node's little input arrow and drag it from the input of the
Viewer node to the node you want to view.
• You can do the reverse and drag the output of the node you want to view to the
Viewer node.
Either method will connect the node to the Viewer node's first input, called input 1.
The connecting line that appears between the two nodes is called a pipe . It simply repres-
ents the connections between nodes in the Node Graph ( FIGURE 1.17 ) .
