Setting up Compositor

Heya,

I’m new to Blender so I’m curious how the author of the compositing tutorials set up his windows in the image here:

I’m quite familiar with compositing techniques but I’ve been unable to figure out how to get a ‘full screen’ preview of the composited image (the reason I’m looking at the tutorials). I do know how to split the windows but I have no idea how to get the image preview as seen in the top right in the tutorial image.

Change that Window to UV/Image Editor window. You must have a Viewer Node in the Node Editor, then it will show up in the dropdown menu just left of his yellow circle as ‘Viewer Node’.

Ah thank you! A bit funky but it works!
