FilmKit Fujifilm Camera Skill

Skill by ara.so — Daily 2026 Skills collection.

FilmKit is a browser-based, zero-install preset manager and RAW converter for Fujifilm X-series cameras. It uses WebUSB to communicate via PTP (Picture Transfer Protocol) — the same protocol as Fujifilm X RAW STUDIO — so the camera's own image processor handles RAW-to-JPEG conversion. It runs entirely client-side (hosted on GitHub Pages) and supports desktop and Android.

What FilmKit Does

• Preset Management: Read, edit, and write custom film simulation presets directly on-camera (slots D18E–D1A5 via PTP GetDevicePropValue / SetDevicePropValue)
• Local Preset Library: Save presets locally, drag-and-drop between camera and local storage
• RAW Conversion & Live Preview: Send RAF files to the camera, receive full-quality JPEGs back
• Preset Detection: Loading a RAF file auto-detects which preset was used to shoot it
• Import/Export: Presets as files, links, or text paste
• Mobile Support: Works on Android via Chrome's WebUSB support
