    Editing timelapses in Lightroom- looks very different if there´s a small change within the frame




      We´re having some serious issues with editing timelapses in Lightroom (5.6). What seems to happen over and over again, is that if there´s a small change within the frame (such as a bird flying past, people walking), the editing result varies greatly compared to the previoius frame. It´s easiest to understand what I mean by viewing the examples below.


      Here there´s one picture without a boat in the frame, and a few seconds later there´s a boat in a small part of the frame. The camera is set to full manual, and the two JPGs which show the unedited pictures shows that the background and sky in both pictures look exactly the same. However, after pasting the same editing setting on both pictures, the picture with the boat looks vastly different (shadow areas are much darker). It´s the same result weather it is a white boat, a black bird or a person walking in/out of the frame. The picture gets much darker, and leads to some serious flicker in the timelapse which can be impossible to get rid of.


      I assume that as there´s a small change in the histogram when the boat enters the frame, this change affects what Lightroom thinks of as shadows/highlights on so on? The example below has some heavy editing applied (shadows up, highlights down, clarity). You can see the settings that have been adjusted in the screenshots below. Does LR change what it considers shadows/highlights based on the histogram, or are there standard settings? If this is the case, it would be much better for timelapsers if Lightroom had standard values for what is considered shadows/highlights, so that two pictures where the only difference is a person walking on the street or not, would look the same with the same editing settings applied. What I find strange if LR works like I´m asking here, why does the picture get darker whether it is a white boat or a black bird changing the histogram slightly. Shouldn´t they then have the opposite effect of each other?


      Any ideas what is causing the difference, and what I can do about it? Thanks!
