I’m going to show you the highpass tool I developed in nuke.
I got the idea after reading Digital Compositing for Film and Video with Steve Wright.
gives you the difference between a blurred input and the original input. making small details quite noticeable.
The 2 main uses are:
1.) to Aid 2d tracking
2.) to apply a different type of sharpen filter to an image.
Here is the link to download the gizmo. Thanks!
