Can you recover deleted photos from the recently deleted section in your album? I recently deleted all of my pictures and backed them up on an app called Shoebox. I did it to save space on my iPhone 6s. I decided it wasn't for me and everything was out place. It was making things complicated and I didn't want it anymore. I now have all my pictures backed up on the app, but don't know how to sync them all back. I don't know if it's possible, but if it isn't I was wondering if I could recover my recently deleted section? If I can, how do I do it?
If you have a backup you had made before deleting those photos, you can restore from it and you would have all your photos. Restoring photos from the 'Recently deleted' section, however, is impossible as of now. 

You can find more information about restoring from an iTunes or iCloud backup here.
