iCloud vs external HD for storage and editing of photos
I have run out of storage on my laptop. I currently have almost 30k original photos on my laptop. I still have lots of organizing and editing to do on these photos.
My question is, which is better? Optimize my Mac photos to keep the originals in iCloud and thumbnail prints on my Mac, or move my whole photos library onto an external HD?
My concern with iCloud is: I read that if storing originals on iCloud then I can't backup my HD pics onto an external HD because it won't recognize the thumbnails pics. I also won't be able to download the originals from iCloud directly onto an external HD at a later time, if I wish. What if I want to do editing on my pics? Can that still be done on my laptop? or do I do it on iCloud? Can I download an original pic one at a time to edit it?
What about moving my entire photos library onto an external HD? How do I sync my photos between all devices using iCloud with an external HD? Is it possible to save edited pics and backup to iCloud from the external HD? I'm guessing once I move my entire photos library onto an external HD then I won't see any photos library on my laptop unless I plug in the external HD? Sorry I don't have much experience with external HD, other than time machine backup.
Note, we also have an iMac and all of my originals are stored on that iMac, it is currently backing up on time machine as I write. I much prefer to use my laptop to edit photos etc.
please advise which route is better for saving and editing my pics, the simpler the better :)
