In one sentence

Yakitsuke is a Mac app that sends your Fujifilm RAF files back to the camera over USB, so the camera’s own image processor develops them with its real film simulations.

About Yakitsuke

Fujifilm cameras can develop their own RAW files, but only one at a time in the camera’s menu or with FUJIFILM X RAW STUDIO. Yakitsuke is an independent Mac app that drives the camera’s converter from the desk: a recipe library, side-by-side comparison of looks, a batch queue that picks up where it stopped if the cable comes loose, and reading and writing the camera’s C1–C7 custom settings.

Because the camera does the developing, the film simulations are the real ones, not presets or LUTs imitating them. Optionally, an AI app such as Claude can use Yakitsuke to try looks on the camera, write recipes and export whole folders.

The name is the Japanese darkroom word for making a print.

What it does

Real film simulations: the camera’s own processor develops the RAF, using its settings for film simulation, grain, Color Chrome, white balance, tone, clarity and more.
Recipe library: nine sample looks, recipes pasted as text, and FP1 files from FUJIFILM X RAW STUDIO.
Side by side: develop the same photo several ways and compare before exporting.
Batch queue: develop a whole roll in the background; it resumes if the cable comes loose.
C1–C7: read the camera’s custom settings, write a recipe into a slot, and back up and restore all of them.
AI agents (optional): connect an AI app such as Claude Desktop and describe the look you want. See real sessions.
