Grainblow is a procedural renoising tool used in compositing.
With Grainblow you can add the effect of an analogue film grain to your renders to enhance the atmosphere, give it the pleasing analogue charm.
The tool is ready to use on Movies, as the grain distribution changes every frame.

In the future, I'd like to rework the scale options and to add some color tweaking options for extreme grainy shots.
All future updates are included!
