LuttieFilm grain effect
Grain that follows the brightness of your image — strongest in the midtones, fading at pure black and pure white. Add it to any photo or video directly in your browser.

How it works
Load your image or frame
Upload a JPEG or PNG, or drop in a video file and pause on a frame. 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
On real film, how strong grain looks depends on how bright each part of the image is. Luttie's grain follows brightness too: it's strongest in the midtones and fades toward pure black and pure white, so it sits inside the image rather than on top of it like a flat noise overlay. It's monochrome, so it adds texture without colour speckle.
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 grain like slow 35mm stock, high size gives chunky grain like fast or push-processed film, or a smaller format such as 16mm. Most natural-looking results come from low-to-medium amount with a size matched to your intended format.
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.
Yes. Luttie decodes RAW files directly in the browser, with no upload to a server. Grade the photo, add grain, and save the finished image in one place. RAW decoding and film effects are both part of Luttie Pro.
