Hello Gunther and the community !
I just shot a "day to night to stars" sequence with a manual lens. So I've input the aperture value when I was asked for. After that, when I activated the holy grail wizard, it gave me a strange curve, which is huge and with enormous jumps (see screenshot #1). Usually, my holy grail curve is (almost) the exact mirror of my luminance curve, but this time it was really weird. I managed to get it back to a decent curve (though it wasn't perfect) by tweaking the two sliders.
But I also noticed that at the very beginning of my sequence, my luminance curve remained pretty even, but the HG wizards detected some jumps (but there wasn't any) that it has tried to compensate (screenshot #2). You can see the luminance values are almost identical but the HG applied two compensations very different. It resulted in a visual preview where the HG has literally CREATED jumps where there weren't (screenshot #3)
I tried to review everything to see if I did something wrong but didn't find anything. So I have 2 questions :
- why did the HG wizard behave like this, creating this curve that is crashing against the upper limit of the screen ??
- why did it "find" jumps to compensate where there wasn't any ? Did I mess something ??
thank you for your help !
