2022 – new section and new articles on the horizon

Happy new 2022! In my WordPress site I have several topics that I started in 2021 but I was not able to finish. I am looking forward to present them hopefully in the near future.

The new topics are not directly related to ACES, that’s why I created a new section called “Exploring HDR displays” on this WordPress site.

One article, at least a first part, I am able to present today. The blurry red star on a cyan background. Since I read the blog from Troy Sobotka I got fascinated with this image. The top image shows how it should look and the second image shows how it looks far too often when you try to recreate this image for yourself.

Dig in into “Understanding pixel values and the EOTF“.


got a small update. With the new versions of the operation systems MacOS Monterey and iOS 15 I need to check again on which devices HDR is supported. There are some strange changes.
For example I could always show my demo files on the iPhone 11 Pro. Now I got a new iPhone 13 Pro and the same page does not work anymore.

I also got the new M1 MBP with an XDR display, so I decided to update the subdomain hdr.toodee.de with some more detailed information on which device and with which browser or app this page actually works as intended.

Check out the updated page on hdr.toodee.de.

Blender 3.0 lighting tests, converting a finished drone footage trailer from SDR to HDR in FCPX and filming with the new iPhone 13Pro in the ProRes format.

Blender 3.0 entered the beta phase, so I thought it is time to update the Blender and ACES 1.2 page. I found a Blender lighting tutorial video on YouTube from FlippedNormals.com and this animated me to follow along with the Blender 3.0beta version.

A fun tutorial to follow along.

At the same time I was testing the latest version of the AMD RadeonProRender 3.3 for Blender as my 2020 iMac has a Radeon Pro graphics card.

I ended up rendering some stills of the sculpture head in Blender 3.0 with ACES 1.2. As the view transform I used sRGB.
The Radeon ProRender does not officially support Blender 3.0, so I used Blender 2.93.5 and Filmic to light the scenes.

My three renders in SDR.

The finished renders I imported into Resolve in ACES 1.3 mode and for the ODT I chose the HDR output ST-2084 1.000 (P3D65limited). My iMac does not show me a proper output on the UI viewer in Resolve, so I simply graded the stills to around 700 Nits peak brightness with the help of the scopes and checked the results on an iPadPro XDR.
For the SDR version, I switched to the ACES/sRGB output and started the color corrections from scratch.

The HDR version or the three renderings.
Why not keyframe the three light situations and create a light animation. Rendered with the AMD ProRender engine and with Cycles in ACEScg and the same light animation, but different shaders and light intensities.

And last but not least, the two render sequences using the OpenDRT (0.090b2 from Jed Smith) display rendering transform and some additional grading in FCPX.

A quick test with the OpenDRT instead of the ACES RRT&ODT.

And here is another little test that I was able to for a personal project of Florian Zachau from Sehsucht that he shot on his SKYDIO 2 drone. He sent me his finished edited and graded project as a UHD ProRes file, I gave it a shot and converted it in FCPX to HDR.

The camera source files and his graded master are done in SDR, but the overall images have already such a big contrast, so it was easy to stretch the sun and lights even further out and make them brighter. I tried to hide the sun disc a little bit more and desaturated areas around the sun. A bit of grain was added and the converted ProRes file handed back to Florian.

Sure, there are compression and other artifacts from pushing the material even further, but on a mobile screen the image looks just cool! Thanks to Florian to be able to add a bit of “spice” to his cool trailer video.

Amazing drone footage shot by Florian Zachau, edited and graded in Resolve.

For the last little project I did a walk alongside the Elbe in Hamburg and filming close to dawn on a sunny autumn day in November.

The shots were filmed just from the hand holding the phone in HD 1080p@60fps in ProRes. The 20 GB heavy clips I imported into FCPX and created a little edit in a HDR/WideGamut. The source files are shot in HLG mode, and I tried in FCPX to to a conversion to PQ, but there is not much more that I could pull out of that footage. So I uploaded the slightly graded film from a ProRes HLG master file.

The same edit, but converted to PQ in FCPX and finished with some additional grading steps.

project: August/October 2021

Here is another project for Genesis called “Vision”. On the website of Infected.digital you can see the client edit and on the website of the director William Armstrong you can see the directors cut.

I just helped out with small Nuke comp tasks and worked mostly on the conforms & online tasks in flame. Last week we finished the directors cut version.

And the next project is available on YouTube. The GV60 from Genesis. More films will follow soon.

holiday links

At the end of my holidays I like to share a list of links of pages and articles that I read, and some videos that I watched or re-watched to learn while relaxing in the south of Spain in my favorite city of Seville. Be aware, it is getting nerdy 🙂

Sometimes it might be helpful to eliminate color when I try to get a better understanding of it. That’s why I revisited an older HDR clip and created a black&white version of it.

projects: June/July 2021

This is the first of some of the recent projects I worked on at Infected. Here are the 15s teaser and the 60s main edits of a commercial for the new G80e from Genesis.

Comp in Nuke and Online in Flame.

One of several projects I worked on in July. This is for “Aktion Mensch”.

house keeping

The menus of this site were getting too crowded with entries over time. I rearranged some of the menu points and brought three topics up on the main menu structure:

  • HDR.toodee.de
  • Learning ACES
  • Understanding ACES

I hope in this way the site is easier to navigate again.

projects: February 2021

After a quiet January without any project, here is the first project of 2021 for Deutsche-Post and DHL. The main task was to “paint” the building outside yellow and slightly altering the age of the actor in one shot plus some display inserts. A fun one week job.


The second project for the month was for MeinAuto.de, a leading online-portal for new cars. I overlooked the whole project in post at Infected.digital, setup comps for first approvals, and comped a bit myself.

project review: 2019-2020

One of the longest projects I have ever worked on: The VW project for the new ID.4 started in November 2019 and I worked on it (with a long corona pause) until July 2020. The project contains two campaigns for two versions of the car. The format mix of 25 & 50 fps on the shoot and later in post-production was a big issue. Delivery formats ranged from UHD 50 fps, over HD 25fps to countless social media formats in 25 fps.
