Despill to Color
in todays quick post I want to introduce you a very handy tool/Gizmo for Foundry Nuke that has saved me a lot of trouble when removing green/blue screen.
If you are trying to fix an objects edge, by bringing back its original color, then this tool is perfect for you! DespillToColor is designed to work best with a specific user defined screen color and therefore a good local solution for certain areas of your plate.
- pick a blue- / greenscreen color - set or pick a target color.
- 'balance' controls how much red tones are being affected by the despill operation opposed to blue and green tones.
- Increasing the 'gain' will affect a wider range of colors, like the finetune knob in DespillMadness.
- Although using 'erode' and 'falloff' - hidden in the info tab - is not recommended it can be a nifty cheat in rare cases. - like when dealing with edge artefacts in the plate.
Gizmo vs Group
For the sake of quickly trying this tool I uploaded it as a group node. Just download and drag and drop it into your node graph.
If you decide to use DespillToColor more often I recommend converting the group into a gizmo. Unlike a group that is loaded from the toolsets a gizmo will always automatically show its controls in the properties panel on creation. How to create a gizmo > https://youtu.be/mGS9viVddMk

https://restore-old-photos.com/ is also worth keeping in mind. For those working on genealogy projects, preserving the original scan is key, but having a restored version for sharing is very useful. I recommend checking out for the enhancement part.
When dealing with old scanned memories or slightly faded images, focusing on tone and detail first is key. I often refer to Pixel Clarity Studio Notes for a streamlined workflow.
When working on genealogy projects, the quality of the source image matters. I appreciate how the Photo Revival Studio Team handles the balance between repairing damage and keeping the original feel of the photo.
ozil goal ai sounds like exactly what I've needed for those stubborn edge pixels. The point about it working best with a user-defined screen color and being a local fix rather than a whole-plate solution makes sense, since spill varies so much across a shot. I like that you can pick a target color too instead of just desaturating and hoping for the best.
planorial seems like a really practical solution for those tricky edge cases where standard despill tools fall short. I appreciate that it lets you pick both the screen color and the target replacement color for more control. This will definitely be useful for fixing problem areas on a key.
