Whats the last photo you took on your phone? Maybe its a selfie, a photo of your family or something random you saw on the street.

Whatever it is, artist Ivan Cash wants to know.

Cash visits different cities across the world where he asks complete strangers what the last photo on their phone is and the story behind it.

As a result, Cash is given access to some pretty private moments in peoples lives.

"I'm specifically interested with this series in playing with the tension between us all walking around with phones that contain very intimate parts of our lives and then being on these phones all the time, which subsequently closes us from the potential for intimacy with the living, breathing people around us," Cash told Laura Vitto of Mashable.
