There is a film called Mystery Train by Jim Jarmusch.
In the film a teenage couple of Elvis fans take the tour of Graceland’s Mansion. They walked around in awe. The boy had a camera around his neck for the whole tour, and yet didn’t take a single photo.
When the couple got back to their cheap bedsit, the boy started taking photos of all the lampshades, the cheap furniture, the bad wallpaper. His girlfriend, slightly surprised, asked him why he was taking photographs of all these dumb things when he hadn’t taken a single photo all day long.
He said, that he would never forget what he had saw at Graceland Mansion, but all this mundane stuff he would soon forget as it wasn’t in anyway remarkable. So he was taking photos of it.
