LR6 (in module development) offers a nice possibilty of half-automatic correction of single parameters like contrast, lights, etc. by pressing shift + double click on the corresponding control bar / text beside the control bar. If I want to apply this simultaneously to some selected photos by activated synchronize option, the modifications are applied with absolute values of the first photo and not individually for each photo. In contrast, if I apply the full automatic correction (of all parameters) to a group of selected photos, every photo get it's individual values.
Side note: It's a nightmare to find a possibility to send a feedback to Adobe. Does anyone know, where to send a feedback like this? In my eyes it's a malfunction of LR and it would be nice, if this could be fixed.
