FAQ
What is the difference between monochrome and color noise?
Monochrome noise adds the same random value to all three color channels (R, G, B), creating a classic black-and-white film grain look. Color noise adds independent random values to each channel, producing a more colorful, vibrant grain effect.
What intensity should I use for a subtle film grain?
For a subtle, natural-looking film grain, use an intensity between 10–25. Values above 50 create a heavy, stylized grain effect.
