Questions preparing for Aperture Independence
Hello - I bought Aperture rather late - about the time they announced it's discontinuation. But I love it as an organizational tool for our 35k+ photos. Our previous organization was using Windows Explorer which is dangerous and difficult to manage - and we never used any keywords. I've decided to keep using Aperture until it doesn't work. After looking around I see two DAMs - Lightroom and Photos - both of which have their shortcomings. Maybe Affinity will come up with a good DAM.
I know some day I will have to leave Aperture. My question is: which Features of Aperture should I use that will be Portable for use in other DAMs such as Lightroom or Photos.
Keywords and other metadata? - Will all metadata added in Aperture stay with the photos after Aperture? Is Metadata saved with the Original Masters or Versions?
Stacks? Will stacks be kept when moving to Photos or Lightroom or will they have to be re-created?
Faces? I believe faces won't move to Lightroom, but might move to Photos. Is it better to create Keyword Metadata for People for portability?
Adjustments? I love the easy tools for touching up the photos, but I understand I will lose these in Lightroom and Photos. If I adjust photos in Aperture I believe I need to export versions which will take up additional space. Is this correct?
Adjusted Data and Time - Some photos are scanned images or photos taken on a camera that didn't have the correct date. I adjust these dates in Aperture. Will these new dates stay with the photo after converting to Lightroom or Photos? Are they written back to the original master or only the versions created in Aperture?
Anything else I'm forgetting?
Thank you for any insight you can provide for the above topics
