UPDATE – Some issues with the original version of the LUT were found by some users, so I have created a revised version and the revised version is now linked below.
Arri Look LUT’s are clearly very popular with a lot of Sony users, so I have created an Arri-Look LUT for the FX3/FX6/FX9/Venice that can be used to mimic the look from an Arri camera. It is not designed to pretend to be a real Arri camera, but to instead provide an image with the look and feel of an Arri camera but tailored to the Sony sensors.
As usual the LUT is free to download, but if you do find it useful I do ask that you buy me a coffee or other drink as a thank you. All contributions are always most welcome. Additionally do let me know what you like about this LUT or don’t like, so I can look at what LUTs may be good to create in the future.

And here is a warmer version (may be very slightly too warm), version 2B.

Alister , I’ve always used LUT’s with Slog3 but have recently had people recommending I use a Color Transform Node in Resolve instead. Do you have any feelings about this or about using Aces , or Resolve Color Management etc. I need to cut a multicam with FX9, AS7siii and some GoPro footage. I’m wondering pros and cons for which method will be the least processor heavy and of course which will give me the best color results.
LUTs were never intended to be used as the actual colour grade and 3D LUTs are not a very good way to transform between colour spaces as LUTs work using a small number of ranges and rely on software extrapolation to fill in the gaps. So anything you can do to avoid the use of LUTs can help improve the final image quality. I am a huge fan of ACES as the workflow is very simple and widely supported. If you use ACES you can move projects between different edit applications as it is an industry standard.
Hi Alister,
You said : “LUTs were never intended to be used as the actual colour grade and 3D LUTs are not a very good way …”
Could you remind us in which circumstances we should use Luts ?
In FCPX I use a Lut as a “ground” grading that I correct and tune. ACs709FX9-65x-V3.0_Base.cube for instance.
Isn’t it a good way ?
The issue with 3D LUT’s is that they do not provide a specific correction for every input value, the LUT would be too big to be practical. So 3D LUT’s break the image up into ranges. A 33x LUT (the most commonly type) divides the image into 33 input ranges and then applies the same correction for that range before moving to the next step in the range and adding the next correction. Depending on the software this can result in steps and banding in the images as it steps from one correction to the next. 64x LUT’s are better as they have finer steps, but even these work in steps.
Hi Alister, for some reason I cant download your new arri luts. The link doesn’t work. Any ideas
I don’t know why it won’t download for you. It is working for me. https://www.xdcam-user.com/wp-content/uploads/2021/10/AC-Arri-Look-V2C.cube_.zip
I’ve tried again and nothing but that maybe my end for some reason. I’ll take a look. Thx for the reply tho
It’s been downloaded 28 times in the past 24 hours and the link is working, so I don’t know why the download is getting blocked for you. Perhaps it’s your ISP or router.
Hey Alister! Is there anyway to get the previous version of the Arri LUT w the slightly pinkish tones? I found that one very pleasing. Also is there a difference between the two versions above? It seems they are the same LUT. Im not seeing the “warmer” tone. Thanks!
Upon further review I noticed reducing the pink in global by about -2 and slightly increasing contrast looks great on the old LUT. Just a suggestion!
Hello, Alister. Thank your for sharing the LUT. Is this LUT supposed to be used with S-Log2 or S-Log3 footage? Because, I use it on S-Log2 footage and it looks great, with good contrast. Would you suggest to use this as a monitoring LUT as well?
It’s designed specifically for S-Log3 and will only provide the expected brightness levels with S-Log3. But, if you like the way it looks with S-Log2 then use it.
Alister , Is this LUT for Post or for monitoring ? In a previous response to a question from me (above in this thread) you said that LUTs shouldn’t be used for Post and suggested Aces. So I tried using Aces and CST for Post in Resolve and indeed they looked very similar to s709 and were easy to use. However I don’t get the point of an Arri Look LUT just for monitoring if a color Space Transform will just look like s709 again.
