  1. Hello,

    This is the official topic for all Colorizer products.
    My main focus is bringing high-precision Fujifilm Film Simulation LUTs to multiple cameras.
    The following formats are supported at the moment, click the links for videos and details:
    Fujifilm X-T3/X-T4 F-Log
    Sony S-Log2/S-Gamut3.cine
    Panasonic V-Log L & HLG

    I also sell ACES IDTs for cameras that are not natively supported by Davinci Resolve:
    - Fujifilm F-Log/F-Gamut
    - Nikon N-Log/BT.2020
    - Sony S-Log2/S-Gamut3.cine
    - Z Cam ZLog2
    - GoPro Protune
    These packs include a lot of 3D LUTs simulating the ACES Rec.709 look, so it can be valuable for Premiere users as well.

    I also have Technical fixes for common color shift issues caused by bad interpretation of certain clips in Premiere. I strongly suggest you check this out if you're a Fujifilm user.

    As a bonus I created a bunch of free online tools for creating and modifying 3D LUTs, so if you're into this kind of stuff, visit http://colorizer.net.

    Thank you for your attention,

    It must be pre-baked data sets of some sort ('assemble on site'). What Cpu are you rockin'?

    It's an old i7-3770. One of the reasons I use Matlab is that many of it's commands are internally multi-threaded, it saves me a lot of time, especially with this old machine.

    I gave it a spin a few weeks ago; sometimes it works decently, and sometimes less so. Here's a comparison of GH5 and Arri, as well as their gradient charts:


    Yeah, it's pretty far from being accurate. I wonder how they do their conversions on the fly, and what precision they use. When I build my camera matching LUTs it takes 1-2 minutes with all cores used to the maximum to build a size 65 LUT, they do it in a second or so.

    Would be interesting to know how Emotive Color stacks up against the new Cinematch plugin from the guys behind Filmconvert. From what I've seen it looks pretty promising...

    I just tested it on some Sony A6300 S-Log2/S-Gamut3.cine and Fuji X-T3 F-Log/F-Gamut clips and if you're after a precise conversion, the results are far from great. It can still be a timesaver though.

  5. Just finished a new tool, it does what the title says. It's in beta, bugs are possible. [CLICK HERE]

    Fuji just released the Bleach Bypass LUT, which has some weird transitions, so I'll use it as a demonstration.

    This is the stress test image I'll use:



    See what happens when you apply the Bleach Bypass LUT:



    Now I use my tool in "box" mode with 1 iterations to create a new LUT:



    This is "box" mode with 5 iterations:



    More details on the site.

    Well I guess it's called bleach for a reason... 😁

    I'm sure you can fix it with your nice package of tools 😉


    A simple LUT smoothing fixes it, it's easy to do in Matlab, but I couldn't create an online version yet. It's on the todo list :)

    About the BT709 LUT, I can't seem to find FLog color space in the Color Space Transform, only the FLog gamma seems to be there

    FLog uses the color space defined by Rec.2020.

    He has done an excellent job of matching color spaces solely using color tools. A 3x3 matrix is kind of like a uniform accordion of R,G & B space, the cleanest tool for the job. The unique advantages to this approach are its tweak-ability, and that it won't clip boundary data in Resolve if you place a grade before the powergrade (grade after though; preserve core logc)

    You are right, and you are a gentleman, because you didn't mention, that for ultimate precision your LUT is still the way to go. A matrix can get you close when you're lucky, but to transform all the color tweaks of a manufacturer, a 3D LUT is still the way to go.

  9. European price:

    FUJI X-T4 1.799 Euro
    FUJIFILM X-T4 + FUJINON XF18-55mmF2.8-4 R LM OIS 2.199 Euro
    FUJIFILM X-T4 + FUJINON XF16-80mmF4 R OIS WR 2.299 Euro

    Does anyone know if there's a way to check which profile (Film Sim) a shot was using? With BMD cameras, my metadata reading app thing tells me whether I was shooting in FILM or VIDEO or EXTENDED VIDEO - but it doesn't seem to get that kind of info from the Fuji...

    Try exiftool. I believe that there's a FilmMode tag that has the info you need.

    Not to be disagreeable but, I'm actually looking forward to shooting creative pieces with different film sims. Something about committing to a look BEFORE rather than the post-processing hell that comes with AFTER that is appealing to me... I think the amount of things I've had to do recently to fix-it-in-post because we liked "options" or were "indecisive" (read: unprepared) might be influencing that.

    I also really liked Classic Negative when I applied it in Capture One Pro to some portrait studio work -a greener finish compared to Classic Chrome. I *hope* it comes to the X-T3...

    I think I'll buy the X-T4 so I'll add Classic Neg to the Colorizer X-T3 F-Log LUT Pack, IF Fuji didn't change F-Log implementation again. But I hope it comes to the X-T3 as well, I'd like to have it on photos straight out of cam.

    i remember when I had the XT3 that, while I dug the colors a lot, the highlight roll off was pretty harsh. Is the XT4 going to be better?

    Did you try DR400? Or use F-Log and create any kind of rolloff.

    Slightly bigger body than X-T3

    Improved IBIS mechanism

    16bit RAW stills

    ISO 64

    6K 60P in 2.4:1 crop

    Which sensor is this?

    Crazy as it sounds, that's a possibility. My main concern there is bit depth density; SLog would probably not be the focus. The GH5S is next around the corner

    I have some experience with that, one of my LUT packages is based on measurements from an A6300 (S-Log2). Without going into details, I think you can create a product that satisfies most people, but it won't be up to your standards.

    Is th X-H1 a relavent camera in 2020?  How does it compare to the newer Fuji cameras for video?

    You already know the difference in specs, but do you want to shoot log? If yes, then the X-T3 is highly recommended over the X-H1.

    Instead of doing a CST -> adjustment -> CST can you just use a single node and set the CS of the node (it's in the menu you get via right-clicking the node) and would it do the same thing?  My understanding is that the CST is simply a user interface to the same RCM functionality that applies to clips in the media pool, timelines, etc.. 

    Changing gamma and color space with the right-click menu on the node only works if your timeline gamma and colorspace is set according to the clip you're viewing.
    So if you're viewing an F-Log clip, and you're timeline is set to Fujifilm F-Log, you can right click the node, set gamma to linear and adjust exposure with the curves the way I described before. It will be like a node between two colorspace transform nodes, but compressed to one node. But what do you do when you have clips from multiple cameras? I like the color space transform plugin better because I can see better what's happening. And sometimes you want to see what's happening between the transformations, in our case the linearized image. When you use the one-node method you don't get to see that, you only see the output of that node.
