True grain structure
Procedural noise modeled on silver-halide patterns and matched to your sensor size — dimensional grain, never a flat overlay.
Analog soul · Digital negatives
Real film grain, at digital speed.
Grainhaus rebuilds 41 classic film stocks from scanned negatives — halation, silver structure and all — and lays them over your photos in seconds.
The emulsion engine
Built from scanned negatives
Forty-one film stocks
Portra warmth, Tri-X bite, Ektachrome blues. Every profile is measured from real negatives, not eyeballed in an image editor.
Full darkroom control
Dial in grain size, push processing, halation glow and vignette with sliders that behave like actual lab chemistry.

Word from the darkroom
“My digital files finally look like they came off a roll of Portra. Brides keep asking which lab I shoot on.”
“The grain is dimensional, not noisy. It’s the first photo tool my retouchers didn’t quietly uninstall.”

Frequently asked
Will the grain survive social-media compression?
Yes. Grainhaus renders grain at your export resolution, and Compression Guard mode sizes grain and halation so they stay visible after JPEG and video re-encoding.
Does Grainhaus touch my original files?
Never. Every edit is non-destructive and stored as a recipe — your originals stay untouched, and you can peel every effect back at any time.
Can I sell work processed with Grainhaus?
Yes. All paid plans include a full commercial license covering client work, prints and advertising. The free tier is for personal projects only.
