I am running LR CC2015 and PS CC. My question is as follows... If I perform a LR adjustment to an existing PSD file, eg, a crop or slider adjustment, does that adjustment get written into the PSD file. My experience from a small experiment is NO. I did a crop on a PSD file (in LR) and then exited LR. Opened the PSD in PS CC separately and the crop is not there. I then changed the filename - tried again - same result - no crop. I launched LR again - imported the renamed PSD file into LR and it recognised the crop that I performed on the original PSD. How did it do that???
Is there some way that I can force my LR adjustments to 'stick' in the PSD file - similar to a DNG?
All Lightroom adjustments are written to the catalog and only to the catalog. This is the nature of the non-destructive editing.
To see your edits outside of Lightroom, you need to export the edits to a new file.
