An X-T4 RAW editor, Bleach Bypass to Reala Ace
The X-T4 debuted Eterna Bleach Bypass and brought stabilisation to the X-T line. RAF Film Lab opens its RAFs on Mac, iPad and iPhone in the film you set, and adds the two simulations the X-T4 never got: Nostalgic Neg and Reala Ace.
How do I edit X-T4 RAW files?
Its 26.1 MP X-Trans CMOS 4 sensor writes 14-bit RAFs, and the X-T4 was the first X-T to offer lossy compressed RAW alongside lossless. RAF Film Lab opens every type.
In-body stabilisation of up to 6.5 stops means sharp handheld frames at slow shutter speeds, which suits the detail tools. Clarity and dehaze work on the full RAW, and masks let you sharpen the subject and leave a smooth background alone.

New to your X-T4: 2 more
Nostalgic Neg arrived a year later on the GFX100S and Reala Ace in 2023 on the GFX100 II. Neither reached the X-T4. RAF Film Lab renders both on its RAWs.
Our films were measured on the X100VI. Apple applies the X-T4's own colour matrix when it reads the RAW, so the films carry over, but we haven't published a score for this sensor yet. How we measure.
Can the X-T4 develop its own RAWs over USB?
X RAW STUDIO supports the X-T4, so RAF Film Lab can send a RAF back to the camera over USB for Fujifilm's own develop, or save a recipe as an X-T4 X RAW STUDIO profile.
- Press MENU/OK and open SET UP (the wrench tab), then CONNECTION SETTING.
- Set CONNECTION MODE to USB RAW CONV./BACKUP RESTORE.
- Connect the X-T4 to your Mac or USB-C iPad with a data cable and turn it on.
Camera render is optional. The camera only develops RAWs it shot itself.

Tips for X-T4 files
- Bleach Bypass plus Grain is the X-T4's signature gritty look. Keep Grain modest at 26 MP.
- Nostalgic Neg on golden-hour frames gives the warm, faded highlights the X-T4 couldn't preview.
- Use the vari-angle screen's low angles with a sky mask. Darken the sky with its own exposure and leave the ground alone.
- Turn on iCloud sync and finish on the iPad what you started on the Mac.
X-T4 questions
Can I use Nostalgic Neg on the X-T4?
Not in the camera; no firmware added it. RAF Film Lab renders Nostalgic Neg, and Reala Ace, on X-T4 RAW files.
Does RAF Film Lab open X-T4 compressed RAW?
Yes. The X-T4 is on Apple's RAW list for macOS 26, iPadOS 26 and iOS 26, and RAF Film Lab opens uncompressed, lossless compressed and compressed RAFs.
Does the X-T4 work with camera render?
Yes. Under CONNECTION SETTING, set CONNECTION MODE to USB RAW CONV./BACKUP RESTORE and connect it over USB.
Is RAF Film Lab an X RAW STUDIO alternative for the X-T4?
It develops X-T4 RAWs without the camera, in all 20 films, with a full editor on top. When you want the camera's exact output, it can use the X-T4 as X RAW STUDIO does.
