Hi,
I have a time lapse that I used the Holly Grail process to take. This was a sunset so it should continually be getting darker. The Holly Grail wizard worked well except that it left behind brightness "humps" or hills after it processed the image sequence.
I am referring to the graph of the mean brightness. To see these hills better I did a second pass export of the sequence and looked at that export with LRTimelapse. This clearly showed those hills in the otherwise decreasing exposure graph. Setting different "deflicker" regions to measure different portions of the scene all showed these little hills of brightness.
I am not sure if I choose a wrong option somewhere or not. It seems I get these no matter how I tweak the Holly Grail wizard.
One of the camera adjustments did move the exposure in the wrong direction and that seemed to contribute to the biggest hill. All other camera adjustments looked to be in the right direction though.
Just wondering if anyone else has experienced this. It still maybe something I did or am doing wrong. I just can't seem to figure out what it might be.
Thanks for any info or suggestions anyone might have!
