All my photos have portrait mode disabled
Hello everyone, I'm Christophe from France.
I have an iCloud Photos Library with 90.000 pictures, all organized, tagged, synced with 3 Macs on macOS High Sierra 10.13.4 and my iPhone on iOS 11.3.
Many days ago, I want to share the latest family event, and realized that all my pictures that were made in "Portrait" mode have the "Portrait" mode disabled, and the blur effect disappeared...
When I edit my photos on Mac or iPhone with "Photos" app, I see the "Portrait" button, but it is disabled by default and I have to reedit every picture to reapply the blur effect. This is very annoying because I have a very large number of pictures.
How can I reactivate the "Portrait" mode to all my library without reediting one by one every picture ?
Thanks in advance (and sorry for my bad English),
Christophe.
