Up until recently, changes to a file processed and saved in PS 2021 merely updated that same file in LRc. Now, when I save new changes to a file in PS, a new file is generated which must be imported into LRc, and that also adds a sequance number to the new file - _2, _3, _4, etc.
How do I get the old behavior back that just updates the orginal file?
Are you saying that in order to achieve the behavior I want, I must always open the file to PS from LrC, using Edit Orginal..
If you 'Open' the TIF file from the OS File Browser, or Adobe Bridge, then Lightroom-Classic has no knowledge of the edit changes you make to the file, and Ps will try to protect your orginal by making the -2 -3 copies when it 'saves'. LrC has no knowledge of these 'new' files either- thus the need to Import!
