I have 7000+ photos in Aperture, how can I import them into Lightroom?
I went to import and my Aperture DB is greyed out.
Do I have to export all the files to import them in lightroom?
First in Aperture, ensure that all the photos are "referenced". Use the relocate masters command, which moves them to a regular folder on your hard drive.
Now, do you want to keep any keywords and other metadata? There's a menu command Metadata> Write IPTC Metadata to Master.
You should now be able to import those files.
PS I assume Aperture 3
