How to Use Fujifilm Official LUTs on iPhone to Add Film Simulation Looks

For both photography and video

Fujifilm has started offering official 3D LUT downloads that recreate Fujifilm film simulations as .cube files. Their own “How to use” notes are simple: download the ZIP for the camera model, unzip it, and import the .cube into your editing software. 

Even though the download page is organized by Fujifilm camera models, the LUT files themselves are standard formats that you can also use on iPhone in apps that support LUT import.

What matters most is workflow: on iPhone you usually cannot “add Fujifilm film simulations” inside the built in Camera app directly, but you can (1) monitor and optionally record with a LUT in a pro camera app, and (2) apply the LUT during editing for both photos and videos.

1) Get the official Fujifilm LUTs onto your iPhone

Step 1: Download from Fujifilm

Go to Fujifilm’s official 3D LUT download page, pick the model package you want, and download the ZIP. 

Step 2: Unzip and store in Files

Unzip the ZIP so you can see the .cube files. Save them somewhere easy to find in the iOS Files app, such as iCloud Drive or On My iPhone.

Step 3: Pick a compatible LUT size if there are multiple folders

Many mobile apps prefer certain LUT “grid sizes.” For example, Blackmagic Camera supports industry standard 17 point and 33 point 3D LUT files. 

If an app refuses a LUT, try a 33 point version first. If you only have a size that your app will not accept, there are utility apps that can resample and export .cube LUTs into common sizes such as 65, 33, and 17. 

2) Video on iPhone: shoot and apply Fujifilm LUTs

Option A: Use Blackmagic Camera to monitor a LUT while filming, and optionally bake it in

Blackmagic Camera is one of the cleanest iPhone workflows because it supports importing LUTs, turning a display LUT on or off, and deciding whether to record with the LUT applied. 

1. Put your Fujifilm .cube files in the Files app.
2. Open Blackmagic Camera, open Settings, then LUT Selection, then Import LUT.  
3. Enable Display LUT if you want to preview the look while filming.  
4. If you want the look “baked in” to the clip, enable Record LUT to Clip. If you want flexibility for grading later, keep it off and apply the LUT in editing instead.  

Important note: Fujifilm’s film simulation LUTs are often intended for Fujifilm log workflows such as F Log, F Log2, or F Log2C, and Fujifilm publishes technical documents and IDTs for those spaces. 

If you apply a LUT made for one log space onto footage from a different camera and log curve, the look can be “in the neighborhood” but not a perfect match. The practical fix is to test a few LUTs, then reduce LUT intensity, adjust exposure, and correct white balance until skin tones and neutrals look right.

Option B: Use Filmic Pro if that is your camera app

Filmic Pro on iOS can import .cube LUTs, use them for preview, and also burn them into the recording if you choose. 

This is similar to the Blackmagic approach, just inside a different camera app.

Option C: Apply Fujifilm LUTs in LumaFusion while editing

LumaFusion supports importing LUT files and applying them during edit. Their official instructions are: use the Import button in the Library or Color and Effects editor, navigate to where the LUT is stored, select it, and open. 

A simple editing recipe that works well on iPhone:

1. Import your clips into LumaFusion.
2. Apply a basic correction first (exposure and white balance).
3. Apply the Fujifilm LUT.
4. Lower the LUT amount if highlights clip too hard or skin becomes too saturated.
5. Finish with small tweaks to contrast and saturation.

If a LUT looks selectable but is grayed out, LumaFusion notes this can sometimes happen due to LUT identifiers used by other apps, and suggests workarounds such as moving LUTs into Files and trying again. 

3) Photography on iPhone: apply Fujifilm LUTs to still images

What you can and cannot do

The built in iPhone Camera app does not offer a “load LUT” feature, so you generally capture first, then apply the LUT in editing.

A reliable LUT workflow: Photomator on iPhone

Photomator explicitly supports importing custom LUTs in .cube format on iPhone and iPad, and it saves them to your LUT library so you can reuse them. 

Basic steps:

1. Shoot with as much flexibility as possible (RAW or Apple ProRAW helps if your device supports it).
2. Open the photo in Photomator.
3. Open the LUT tool, then choose the option to add or import LUTs, and select your .cube file from Files.  
4. Apply the LUT, then fine tune exposure, white balance, and tone.
5. Save or export.

Because film simulation looks are sensitive to white balance, you will usually get better results if you correct white balance before or immediately after applying the LUT, especially for indoor lighting.

4) Troubleshooting checklist

1. The LUT will not import
   Make sure you unzipped the download and you are selecting a real .cube file. Fujifilm’s own instructions emphasize unzipping and importing the .cube into editing software.  
2. The LUT imports but looks wrong
   This is usually a color space mismatch. Fujifilm provides separate log technical documents and IDTs, which is a clue that the transforms assume specific input characteristics. 
   Try a different LUT variant, reduce intensity, and fix exposure and white balance first.
3. The LUT is rejected due to size
   Use a 33 point LUT when possible for mobile apps, since Blackmagic Camera supports 17 point and 33 point LUTs. 
   If you must convert, use a LUT utility that can export common sizes.
