What a RAF file is
RAF is Fujifilm's RAW format. Most X-series bodies use the X-Trans sensor, whose colour filter repeats every 6 × 6 photosites instead of the usual 2 × 2, so a converter has to demosaic it differently; GFX bodies and a few X models use an ordinary Bayer filter.
Cameras that record RAF include the X-T5, X-T4, X-T3, X-T2, X-T30, X-T20, X-S10, X-S20, X-E4, X-Pro3, X-H2, X100V, X100VI, GFX 50 and 100 series.
The JPEG inside a RAF
A RAF file also carries the JPEG the camera made: 1920 × 1280 on an X-T2 and an X-T20, a fraction of the 24-megapixel sensor. The X-Trans demosaic here works at full size. The film simulation you chose in the camera is not in the RAW data, so the developed colour is neutral, not Provia or Classic Chrome.
Converting RAF to JPG here
- Drop one or many RAF files on the converter, or choose them.
- Keep “Develop the RAW” for the full sensor, or choose “Use the camera's JPEG” for its exact look.
- Choose JPG (and its quality) or a 16-bit TIFF, the size, and the brightness if the camera's was not what you wanted.
- Press Convert. Each file can be downloaded as soon as it is ready, or all of them as one ZIP.
What it does not do
- No lens corrections: distortion and vignetting that the camera removes from its own JPEG stay in the developed picture (most visible on Micro Four Thirds).
- No sharpening and no noise reduction: the developed picture is what the sensor recorded, which at 100 % looks softer and grainier than a camera JPEG.
- No picture styles or film simulations: the developed colour is neutral. The camera's own JPEG keeps them.
- Apple ProRAW and other already-demosaiced (linear) DNGs are refused by name, not guessed at.
- Memory: a 24-megapixel file needs about 0.5 GB while it is developed, a 60-megapixel one about 1.3 GB. Files are converted one at a time so a batch does not add up.
