This video is every reason as to why I use your DCTL's 😅 I'm absolutely done with LUT's in my workflow - they're guessing at best, they often make the image fall apart very quickly and they provide no gratification or fun in the process of grading an image 😊

Wow, that was interesting! Never seen that testing method before! Makes spotting (badly) designed LUTs so much easier. Thank you :)

Nice, I have leaned something new today. When a lut it applied, it should not impact a smooth gradient otherwise, the image will struggle in the color where the gradient had issues.

Hi Stefan, thanks for the great ressource. What is your input colorspace and input gamma on your timeline when using the color gradiant ? As you change form it to colorspace needed by the lut.

In my testing process, I use a CST to convert the test image to the color space that the LUT expects. It's worth noting, as I mentioned at the end of the video, that this method isn't 100% accurate. The color rendition isn't going to be exactly what you'd get if you were working with original footage shot in the intended color space. However, it does provide a good initial impression and can still be a valuable part of the stress testing process for the LUTs.

Hi @@StefanRingelschwandtner ! To be sure i'm not making a mistake in my CST Is your RGB test charts in SRGB linear gamma ? thanks for your amazing work

@@davidhtz9438 The RGB test charts are in the standard sRGB gamma, which is not linear but has a gamma value of approximately 2.2. They are designed to match typical display conditions. If you need them in linear gamma, you would have to apply the appropriate conversion.

oh gosh ! The only stress test I was able to find was the one released 9 years ago ! Almost nobody's speaking of this. But I watched an itw with the colorist of "joker" and other big production. And they are stress testing with real images and not technically pure... I think we are too strict to ourself ! xD

Is there a way to fix these? I am currently trying to design 2 things. A standard conversion LUT for me as a base-line, and a proper 2383 LUT for monitor on set. My camera is Sony F35 so it's CCD and may act differently, and SLOG1 isn't really getting that much attention anymore. My conversion LUT seems alright so far, but the 2383 LUT tends to have cyan/blue in the highlights when I monitor the curves in Lattice.

What would be the best source to learn how to create a proper LUT?

You can try searching for the "Showlut Design Course" by Cullen Kelly, or you might want to check out the "Demystify Color" website by Nico. Learning how to build a cube in Fusion could also be beneficial. Additionally, aim to deepen your understanding of color science continuously. This should include learning about color spaces and related topics.

Not to be rude, but can't you test it yourself now after watching this video?
