how to recover my deleted photos

The only place where you can recover deleted photos is the Recently Deleted album. Photos is keeping the deleted photos there for thirty days, so we can put them back. When the thirty days up, or we empy recently Deleted before this time, the photos will be permanently deleted. Then we have to fall back onto our backups we made, when we still had the photos. See: If you're missing photos or videos in the Photos app - Apple Support (IN)

Hi léonie. I've read on a variety of sites that there's more methods to recover lost photos. A few people gave details on how they asked for a higher level Apple Support agent and photos, videos and iMessages were recovered long after 30 days and it did not require restoring from a backup or a 3rd party product. Can you shed any light on this if you know of anything? Thank you!
