how to create a new library , merge libraries keeping captions
Some assistance required please regarding Photos on my iMac.
Over the years and OSs I seem to have several photolibrary's one of which contains some slides that were scanned many years ago into a ".pct" format. Somehow they now no longer show only a large "! mark" .
I have now re-scanned them all and wish to consolidate my photo library into one retaining all the descriptions of when, where & who is in the photo and keep them with all my other pics in the one library.
Can this be done safely on my iMac?. I have looked at many reports and suggestions on-line. My proposal is firstly do backups of each library;
Make a new system Photolibrary.
Select all from each "old" library and import into new library.
If successful, I can then delete the old libraries freeing up space on my iMac.
This may seem an easy operation but can anyone give some more tips and advice please?
