bonjour

my english is not very good, sorry, i will do what i can !
I have a problem with my sequence of shoot holy grail. I think the aperture of my canon 5d mark ii isn't steady. Then i have a "jump" that i can't deflicker. I don't change setting of photos 5445 and 5446 (f/9 1/8s 800 ISO). But there is a difference between both.
I make deflicker at 25, 2 passes, default, but it does not work. How i can deflicker this ? How i do if i want to smooth only a part of the sequence ?
thanks !

Please set a proper reference value before you deflicker such sequences. Check out my deflicker tutorial on https://lrtimelapse.com/tutorial/ in order to learn how.
If then Deflicker with some passes doesn't solve the problem, it's not brightness flicker, then it's something with changing contrast, which might be introduced by heavy editing in Lightroom.
See this faq: https://lrtimelapse.com/news/use-the-new...me-lapses/

ok, i'm looking for the links. As i didn't arrive to solve this flicker on one image, i didn't think the problem don't be in this picture. Opening the photos in camera raw without settings, there's no difference... It's haze generate the probleme (value 35, it's beautful sky, but finally that generate also color drift). I will rework my sequence, thanks a lot.
I didn't take many holy grail, it takes practice

Hi,

in case your problem didnt resolve, i would try to set a proper (blue ones) keyframe on both frames (620 and 621, as shown in your picture) in LRTimelapse , save them and than go to lightroom, reload the metadate and ajust both frames manually until they match each other.

That usually works quite well, i hope that helps
