Photographer seeking mystery couple seen in epic Yosemite picture

A photographer from Michigan captured a very special moment at Yosemite National Park and now he's on a mission to track down the photo's mystery subjects.

If you look closely at the photo, you can see a couple getting engaged in the background.

Matthew Dippel says he was taking a picture of Taft Point when the couple walked into the shot and he captured the proposal.

He posted the photo on Twitter, hoping to find the couple and share the picture with them.

He took it on October 6, but so far, he hasn't found the couple.
