Guenther,

I watched your video on deflickering for LRT5 and am using a panoramic head for  motion time lapses.  In my timelapse, I am making a 180 degree sweep with the camera with the main subject being the sky.  However, in the middle of the timelapse, a tree enters into view for a few seconds before transitioning to the sky again, and my question is the following:

How do I create a reference frame for deflickering in the scene that basically skips over the tree and just focuses on the sky during the 180 degree panning motion?

Thanks,

Carl
