A Question of Credit - Who Gets It?

Who gets the credit for this shot - Selfie Scenario:

I'm out with MY CAMERA. I carefully select a scene for my background. I meter the scene and set all the settings on MY CAMERA - ISO, focal length, aperture, shutter speed, etc. I determine exactly where the picture should be taken from.

I hand MY PRESET CAMERA to someone else, make sure they stand exactly where I want, and tell them how to frame the picture. I then jump into the picture and then tell them how and when to push the button.

Who gets credit for this photo? The person who pushes the shutter button? Or the person who did everything else?
