How to retrieve deleted photos on iPhone?

I recently transferred all my photos from the camera roll on the iPhone onto the computer. After thinking I've copied everything, I permanently deleted all the photos on the phone. I found out I had lost quite a few photos from around a month ago but I had not backed my phone up for half a year. Is there a way to get back permanently deleted photos?

To recover deleted but not backed up iPhone photos, you have to use an iPhone data recovery. Search one from the internet. Here, I personally recommend Tenorshare iPhone data recovery, it recovered my iPhone text messages before.
