How to get pictures back that you deleted from the iPhone?

Is there a way to get pictures back that you deleted from the iPhone?

Here are 2 effective ways that can help you recover your photos from iPhone:
1. Directly scan and recover pictures from your iPhone.
2. If you've synced your iPhone with iTunes, you also can regain your deleted photos by extracting your iTunes backup file.

Restore your iPhone from a previous back up:
1) Connect your phone to your computer with the USB cable
2) Open up iTunes
3) Right click on it within the Device menu
4) Click on Restore from back up
5) This will restore it to the settings of the back up with everything that was on your iPhone at the time

(Everything gets restored to that point: Photos, Safari data, apps, settings, contacts, emails and photos)

I don't think so. Hopefully, if you have synced it recently it would be a bit easier then. Hope I helped.
