If you like to share or edit Photos, iPadOS 13 is probably worth an upgrade.
With iPadOS 13 on board, when you open a photo or another option to share, there are now suggestions based on your actions.
We use AirDrop a lot and on iOS 12 it can take anywhere from a few seconds to a minute for the AirDrop option to show up. With iPadOS 13's changes, it's always in the top recommendation for photos.
iPadOS 13's new share sheet also offers up faster access to apps you may way to open the item in and functions like copy and paste.
The new Photo editing options in iPadOS 13, and the setup, make it easier to see what you are trying to do and to find changes that will make your photos look better.
On the photo side of things, this is a facelift that makes it easier, but with videos you now have access to many of the same editing options and you can even rotate a video that you shot in the wrong orientation.
It’s also much easier to edit movies. You can tap an audio button to automatically make your movies look better and you get many of the same photo controls for editing movies.
