Hi,

I just got a message from one of my students who has an issue using the Holy Grail Wizard. It is not fixing the exposure jumps correctly.

I asked him to sent me the image sequence to test it myself and I'm experiencing the issue as well with v5.6 and the latest beta.
I started fresh with initialized metadata.

- Holy Grail curve: https://i.ibb.co/WPCzSLx/lrt-holy-grail-1.png
- Visual Preview curve https://i.ibb.co/p3DY86y/lrt-holy-grail-2.png

The sequence was shot in manual: https://i.ibb.co/z8yt4Xb/lrt-exif.png

I'm using Windows 10 Pro x64 21H1 19043.1110

Code:

So what happens after a couple of visual deflicker passes? Still not smooth? AHG always goes along with visual deflicker and an appropriate reference area. Cameras often don't write accurate values in the exif data that a mathematical approach like AHG alone would instantly deliver the desired results, that's why in many cases you also would need a visual approach additionally.

Deflickering the sequence works like a charm, but I was wondering why the Holy Grail wasn't working properly. But you just answered my question, so I'll pass on the message to my student.

Thanks Gunther!

Also recommend him to do smallest steps {1/3 stops) when adjusting the camera and set the reference area in LRT before applying the HG wizard.
