How to stop Photos.app automatically opening when you insert memory card

In Apple’s OSX operating system 10.11 El Capitan, the Photos app is set to automatically open when you insert a memory card. While you can change that on a per card basis, when you format the memory card the app will open again.
There’s no setting in the app to stop this, but you can do so using a command line in Terminal to change the name of the helper app. There’s an extra complication with OSX 10.11. Apple has added a new protection layer where certain apps are marked as Protected. Photos.app is one of these apps and to change it, another step is needed to disable the protection layer called SIP. Here is a step by step guide.
