Everything you need to know about Film Grain
Film Grain adds realistic analog film texture to your digital images. Recreate the organic, nostalgic look of high-ISO film photography with customizable grain size, color variation, and tonal distribution – just like real film stock.
Parameters
- Strength
Controls how much of the grain effect is blended with the original image. At 0, no grain is visible. At 1.0, the full effect is applied. - Amount
Sets the intensity of the grain. Low values (0.05–0.15) add subtle texture. Higher values (0.25–0.50) create a gritty, high-ISO film look. - Grain Size
Controls the scale of the grain particles. Small values (0.25–0.75) create fine, tight grain like low-ISO film. Larger values (2–8) produce coarser, more prominent grain like pushed film. - Color Grain
Adds chromatic variation to the grain. At 0, grain is pure monochrome (luminance only). At 1.0, each color channel has independent noise – mimicking color negative film's characteristic colored grain. - More Grain in Shadows
Concentrates grain in darker areas of the image. Real film shows more visible grain in shadows, so higher values (0.7–1.0) create a more authentic look. - More Grain in Highlights
Adds grain to brighter areas. Typically lower than shadows for realism, but increase for stylized effects or to simulate overexposed film.
Tips
- For classic 35mm film: Amount 0.15–0.25, Size 1.0, Color 0.3–0.4
- For gritty high-ISO look: Amount 0.35+, Size 1.5–2.5, emphasize shadows
- Combine with Color LUT film presets for complete analog simulation
- Keep highlights lower than shadows for the most natural result
