How to recover deleted photos from iphone or iTunes

As far as I know, there are three ways to restore lost photos from iphone or iTunes:

1. If you have backuped your photos before, you can restore the photos from the backup files on the computer, whether it’s from iCloud or iTunes.
a. Check iTunes for a recent backup: In iTunes, go to Preferences > Devices. If there is a recent backup listed here for your iPhone, you can reset now and restore from this backup.
b. Check iCloud for an automatic backup: You may have enabled automatic backups to iCloud. If your data is available at iCloud, you can reset now and restore from here.

2. If you have uploaded your photos to cloud drives like Google Drive, Dropbox before, you can recover the photos from cloud.
