Visualizes grain by differencing a Cineon plate against a light blur, then lifting the residual so grain structure reads clearly in the viewer.
Grain Check is a utility group that makes film or digital grain easier to judge. The incoming image is converted to Cineon, split so one path is lightly blurred, then merged with a difference operation. A tight whitepoint grade amplifies the residual so high-frequency grain stands out without changing your main comp tree.
Use it when matching grain between plates, checking grain after denoise or resize, or comparing stock before you commit to a grain node. Drop it over a plate or a graded branch, view the output, then disable or remove the group when you are done.
Internal values are fixed: Cineon colorspace conversion, a small blur, difference merge, and a low whitepoint lift. There are no exposed grain amount or size controls; the gizmo is a diagnostic view, not a grain applicator.
