And that is well supported in iCloud Photo Library, the only seamless way to transfer a Photos Library with all edits, albums, favorite tags. You do not need to upload your complete Photos Library to iCloud, if you do not want to purchase extra storage. You could create a new, empty library just for downloading from iCloud.
According to Apple it's all or nothing when uploading my photos to iCloud. I could then download the albums I want on my computer.
If you prefer to stick with the older way - My Photo Stream - to transfer photos, it is your decision. It is very unlikely, that Apple will change the way My Photo Stream is working, because it is essential as a support for older devices, that cannot be updated to newer versions of iOS and iCloud Photo Library, and it would mean, that Apple would have to release iOS updates for the older devices.
Apple doesn't seem to think that way when they update their iOS and stop supporting older equipment.
My Photo Stream is a temporary buffer to transfer your new photos. If you import a photo, or take a photo with the camera, or save it to the Camera Roll, it will be added to My Photo Stream immediately and remain available there for at most 30 days. My Photo Stream will hold at most 1000 photos You have to save from My Photo Stream, while they are still available. Because the photos will upload to My Photo Stream, as soon as they have been aded to your library, they cannot hold the edits, only filters you applied already in the camera.
If there are photos missing from my Photo Stream, that are newer than 30 days, something is wrong. Only the videos or the Live Part of Live Photos should be missing.
But My Photo Stream should transfer the edited version as well, if you save it to the Camera Roll. Only it is a bit tedious to have to save the version separately as described above.
- I am aware that Photo Stream is just a temporary importing of photos and only keeps the last 1,000 photos. I save my photos from Photo Stream into the specific albums I want them in.
- When you edit a photo, it is automatically saved to Camera Roll and the new version is not always added to Photo Stream.
Eventually, something will change or I will only just use 3rd party software to edit my photos, which certainly is more work than being able to do everything in iPhoto and given a choice of how to save the edited version.
Again, appreciate your follow through and response.
