Trying to Understand iCloud Photo Storage

[vision63]

For the time being, check out the pros and cons of "Optimise Photos" in the iPhone settings. I've been meaning to fully check out how Apple implements this feature.

Settings

General

iPhone Storage

Enable "Optimise Photos"

It should reduce quite a bit.

The photos are still stored on iCloud and the phone photos are replaced with smaller versions. When you want to do something with the photos it "should" retrieve original seamlessly.

If you don't do the Optimise feature, anything he deletes from his iPhone also gets deleted in iCloud.
