Is it possible to have multiple watched folders, each of which importing to a different folder within my Lightroom library?
Reason being, I have set my iPhone to automatically upload any new pictures or videos taken into the watched auto-import folder, which then takes those photos and puts them in my Lightroom library in my "iPhone" folder for filing and post-processing later.
Now my wife would like the same thing for her iPhone as well... but I don't want to intermingle our photos. Is there a way to set up a second watched folder, that could follow separate importing rules?
No, only one watched folder is allowed, but Lightroom should read the phone's serial number. So you could use the Library Filter or smart collections to identify your and her phone photos.
