  • OpenColorIO-Config-ACES 2.0.0 available (09/2023)

    There is a new OCIOv2 config available. Check the link for the updates.

    The name of the release is a bit confusing again, because the config contains:

    • New configs in version v2.1.0
    • ACES 1.3, ACES 2.0 is still in development
    • OCIOv2 in point release 2.3

    For me as a MAC user with Display P3 screens, the following feature could be important: “DisplayP3 Related Colorspaces and Display Rendering Transforms”. But I need to test the new config a bit.

    Actually as I am also testing the new Nuke 15 Beta, I saw that Nuke supports only OCIOv2 up to version 2.2, not 2.3.

  • Blender 4.0 – now with AgX

    Blender 4.0 will be shipping with a new OCIOv2 config.
    In addition to Blender FILMIC there will be a newer view transform called AgX.
    As Blender 4.0 is still in an alpha stage, the defaults in the color management area are a bit strange at the moment (3rd of September 2023).

    Here is a little guide how to set some of the settings to avoid running into troubles.

  • Holiday links (06/2023)

    During a two weeks summer break in Seville I took the time to study a bit of 3D rendering background. I found a YouTube playlist from the Technische Universität Wien about the topic: “TU Wien Rendering / Ray Tracing Course“. The course is super interesting, great that this kind of knowledge is available for free.

    I am subscribed already for quite some time to the channel “Two Minute Papers” from Károly Zsolnai-Fehér and enjoyed some of his short videos.

    I also watched some videos about the Mitsuba 3 renderer.

    It was used to generate some test images for the ACES 2.0 CAM DRT Development thread on ACESCentral.com.

    I used that renderings to generate some comparison videos for the discussions on the ACESCentral thread. I wanted to see these renderings through different image formation pipelines like ACES 1.2, ACES 2.0 dev035, ARRI Reveal, Baselight’s T-Cam and AgX in SDR and HDR.


    I also found another video on YouTube called “Practical Aspects of Spectral Data in Digital Content Production – SIGGRAPH 2022”. This is very technical.

    Already before the holidays I found this presentation called “The Full Spectrum of Virtual Production“. Some of the concepts are explained in the Siggraph video as well.

  • Following pixels from Resolve to YouTube

    In this blog post I wanted to see how I need to set Resolve on my iMac so that the image that I see in the Resolve viewer looks the same when I export a Pro Res file of the timeline and view it in Quicktime. And I explored the next steps that are necessary to see the same image in Safari on the YouTube page.

    Continue here to read “Mac,P3-Displays & Resolve“.


    The second part is finished as well: Switching gears from sRGB to Rec.709-A. At the end I tested the new “Remote Monitoring” feature in XDR reference mode as well.


    Somehow I was not finished yet, therefore I continued with FCPX and even did a round-trip back to Resolve again. Fine the third part of this series here.

    FCPX & Resolve can work quite similar.

  • More projects of 2022

    For one of the first projects in 2022, in February I was attending a shoot for a Bosch/Markenfilm/Infected.digital production for 10 days in Prague as the VFX supervisor. The project is finally out now on Social-Media and YouTube.


  • What does a digital camera RAW file store?

    • An image?
    • numbers?
    • A/D converted sensor values?
    • colours?
    • light information?

    When I use a photo develop program like Capture One, Affinity Photo or darktable I don’t really need to care. I am presented with an image, I can tweak it and hopefully get out a good looking digital photo.

    But when I want to know what color an object in a photo has? What do the values in a RAW (or digital native) image tell me? This is the second part in the series “Numbers and meaning” with the second article called “It’s getting RAW“.

  • New year, new chapter

    I thought it’s time for a new chapter on the website again. The chapter is called “Numbers and (their) meaning” when working with digital (image) files.

    Here is a small introduction to the topic and here the link to the first article.

    Is this a red car or a nearly grey car in a greenish tinted image?
