Hey Product Hunt! 👋 I built GrainLab because I missed the feeling of shooting on film — the grain, the color shifts, the imperfections that make a photo feel alive. Every digital photo editing tool I tried felt either too complex or locked behind a subscription. So I built something I'd actually use myself. GrainLab is a free, open-source film photography simulator that runs entirely in your browser. No account, no install, no paywall. A few things I'm especially proud of: 🎞 11 film presets — Kodak Portra, Fuji Velvia, CineStill 800T, and more, each carefully tuned to match the real stock's character 🎛 8 stackable effects — grain, halation, light leak, bloom, tone curve, vignette, fade, color grade 📦 Batch export — drop in 50 photos, apply a preset, download a ZIP 🌍 Available in 9 languages I'd love to hear what film stocks or features you'd want to see next. Happy to answer any questions! → seamys.github.io/grainlab
