Another article is finished for the section “Exploring HDR Displays“. Imagine you work, test and judge images all the time on your nice and big iMac display only to find out that for years I saw different colours in the apps and on exported images that I put up here on WordPress.
That relevation deserved another article called “3.7.2. Working on a P3 Display in MacOS“.
Here is a little “How-To” use Blender with a different OCIO config called AgX.
I like to store and share some links that I found interesting and useful in the last months. Here they are:
A new OCIO v2 config called AgX and a video explaining some of the ideas behind it.
Some interesting insights in DSLR camera native file or also called RAW files.
I watched this video 20 times, but I am still too dumb to repeat the same steps with a scan that I made with Scaniverse or PolyCam. One day I will hopefully understand the right workflow.
I bought the PDF to support the efforts from Grzegorz Baran.
This evening I saw on ACESCentral.com that the download for OpenColorIO-Config-ACES 1.0.0 is available now. I updated the article Blender 3.4 alpha & OCIO v2 accordingly and I will start soon to do some tests in Blender and Nuke.
The ACES 1.2 release candidate is the last version that will be available for the OCIOv1 framework. Newer OCIO configs that support the OCIOv2 framework are at a pre-release state at the moment. I will try to stop using the OCIOv1 configs and switch over the OCIOv2 configs.
When you want to use the new OCIO configs in Nuke 13.2, please be aware that Nuke only can read the name…_ocio_v2.0.ocio configs. The name…_ocio_v2.1.ocio configs are not supported in this Nuke version, but Blender 3.5Alpha for example can read these configs.
Another new behaviour in Nuke is, that you cannot set an output transform in the write node unless you alter the OCIO config by yourself. Output or view transforms are missing in the write node. The workaround is to use a OCIODisplay node at the end of the nuke script and write out the files with a write node that is set to “raw data”.
That is a very bad implementation at the moment in Nuke, because as soon as you view the OCIODisplay node, the viewer itself needs to be set to “raw” as well, otherwise the view transform will be applied twice.
The issue is discussed here. I assume this will be addressed in the upcoming Nuke 14 release.
In the upcoming weeks there should be coming the MacOS Ventura and the iPad 16.1 releases. Of course I will do some HDR tests once the updates are available.
In the meantime I cleaned up the subdomain hdr.toodee.de and the HDR-Gallery pages. Some of the information was already outdated and I re-ordered the example clips to declutter the pages a bit.
Beginning of this summer I started an article, but somehow it was never finished. I added lots of images, but the context was missing. Now I revisited the article and finished it up.
I took just one simple rendering from Blender and viewed it through many view transforms including the three candidates for ACES 2.0, both in SDR and HDR.

This summer I worked on some nice projects at Infected.digital. My role was comp lead and I did the online on flame on all projects and additional comps in Nuke.
A full list of all the recent projects can be found here.
I think I can finish looking at this image for a while now. I finished part four of a series of blog post that I thought would fit into one post initially. But the deeper I peeked into the issues with this image, the longer it took to finish the articles. Here is an overview of all four articles.
Blender 3.2 is out and has a lot of new features. One of them is the color space override in the Scene/Output section. This was a good opportunity to test out a little scene that I have set up. So you could view the left image in Blender …
…but actually render out the right image. This is a stupid example, but it’s getting more interesting when rendering EXR files. Please read the Blender 3.2 render colorspace overrides for more information.
Plus a follow up article rendering a close-up of the same scene and taking a closer look at different display rendering transform (DRT) options:
One Scene – many images
I thought it was time to finally switch the WordPress theme of this site to the new default theme “Twenty Twenty-Two”. I find the overall look is a bit cleaner but I struggle still a lot with the new menu structure. I do not find it intuitive at all.
Also some effects in galleries of the CoBlocks Plugin failed and I needed to repair some older pages so that they look kind of okay again.
I also make some little changes to the subdomain landing page hdr.toodee.de.
It is very frustrating to explore HDR content on websites, beause with every new OS, browser or hardware update suddenly some feature unexpectedly work and other which worked before all over sudden stop working.
It is a moving target. And with Instagram introducing HDR content in Reels there is even more to learn and explore and again the feature is very unpredictable at the moment. I don’t find any official information about how, when and what works regarding HDR Reels.
I hope next week Apple’s WWDC will finally mention some of the HDR features for video and stills. Till today HDR media capability is still labelled an experimental feature in Safari.
