To create timelapses with Lightroom, I take a bunch of pictures, develop one of them as I like, copy-paste the development settings to all and then export a slideshow.
This, however, does not apply the development settings to all pictures. I have to go manually through the pictures (just viewing them suffices). The old version will be shown for a second, then the version with the new settings appears.
Can I automate this task somehow? It feels like it is a bug in Lightroom, but maybe there is a workaround like a command to apply all exposure settings of selected pictures.
Using Lightroom 6.7 with Camera Raw 9.7.
