Remember cameras? They could zoom and flash and focus ... cameras were great. There were even disposable cameras that you could buy pretty inexpensively.

And remember photographs? They used to be physical things. You put them in a book or in a frame or even carried them around in your wallet! Good times.

Now ... we have smartphones. We're taking more photos than ever, but what happens to them? We forget about the pictures we take so quickly that there are even apps that bring old photos to our attention. Thanks, TimeHop!

Thankfully, the site Kind Of Normal has broken it all down for us.
