LuttieFilm Grain Online. Looks like the real thing.
Luminosity-blended grain that behaves like real 35mm film stock — strongest in midtones, fading naturally at shadows and highlights. Add it to any image or video frame directly in your browser.
How it works
Load your image or frame
Upload a JPEG, PNG, or extract a frame from any video file. RAW files (CR2, ARW, NEF, DNG) are supported too.
Apply your colour grade
Grade first — grain sits on top of your colour work, not underneath it. This matches how film grain interacts with developed colour in a real darkroom.
Dial in the grain
Use Amount to control intensity and Size to go from fine 35mm to chunky medium-format. Grain is strongest in midtones and fades naturally at shadows and highlights.
Export
Export your colour grade as a .cube LUT for use in DaVinci Resolve, Premiere Pro, or Final Cut Pro. The graded image with grain is visible on your canvas.
Why not just use Premiere's Noise effect?
Flat noise overlays apply uniformly across all tones. Real film grain doesn't work that way.
Uniform noise (Premiere, After Effects)
- ✗Same intensity in shadows, midtones, and highlights
- ✗Looks like digital sensor noise
- ✗No tonal awareness
- ✗Obvious at low values
Luttie film grain
- ✓Strongest in midtones, fades naturally at extremes
- ✓Replicates silver halide crystal density behaviour
- ✓Luminosity blend mode built-in
- ✓Natural at higher amounts
Frequently asked
Why does grain look better in midtones?
Real film grain is a function of silver halide crystal density — it's most visible in the mid-exposure range and disappears in heavy shadows (underexposed) and bright highlights (overexposed). Luttie's grain uses a luminosity blend that replicates this, so it doesn't look like flat digital noise.
What's the difference between Amount and Size?
Amount controls how strong the grain is — higher values make it more visible. Size controls the scale of the grain clusters — low size gives fine 35mm grain, high size gives chunky medium-format or push-processed grain. Most natural-looking results come from low-to-medium amount with a size matched to your intended format.
Does grain export in the .cube LUT?
No — grain is a spatial effect (it varies per pixel) and LUTs are pure colour transforms. The LUT captures your colour grade exactly. Add grain as a separate effect layer in your NLE on top of the applied LUT.
Can I add grain to RAW files?
Yes. Luttie decodes RAW files directly in the browser (no upload to a server). Apply your grade, add grain, and export your LUT — all in one workflow.
