Man's epic proposal in front of Northern Lights

After years of planning, a man has pulled off one of the most romantic marriage proposals ever under the Northern Lights in the Arctic Circle.

Dale Sharpe, from Australia, got down on one knee as the natural phenomenon made an incredible display after tricking his girlfriend Karlie Russell into believing he was snapping a selfie in front of the lights.

The couple, who are both landscape photographers, were pictured in front of the dancing green lights in the beautiful proposal. Naturally, Karlie said 'yes'.

Writing on Facebook, Dale said that the lead-up to the proposal didn't exactly go to plan.

He said: "It's taken a few years to plan but I always had this moment in mind & it seemed fitting as we are both landscape photographers who share a passion for photographing the aurora. Originally I was going to propose in Iceland last year but unfortunately Karlie decided to discard my secretly stashed ring (yes, that actually happened lol, we were trying to cut weight on a connecting flight from the Faroe Islands)."

Fortunately when the proposal took place, the Northern Lights fired "one of the most incredible displays of colour we have ever seen," Dale said.

He added: "I tricked Karlie into believing we were shooting a selfie & used a torch to light us up for the image.

"Much to her shock, it wasn't any normal selfie, and much to my shock, she said yes! This is a single image that was taken during the proposal. And now we may not have any of our own images up hanging on our walls at home...we may however...make an exception for this one."

The couple have seen the Northern Lights around 30 times together, which prompted Dale to use the magnificent sight as their proposal setting.

Speaking to ABC7, Karlie said: "I was completely blown away as it was the last thing I was expecting at that time. I kept telling Dale to hurry up so we could get a landscape shot instead.

"After he set up the camera, then to my surprise got down on one knee, I was in shock but of course said yes! I couldn't think of a better backdrop for the proposal or for the sneaky 'selfie' that he managed to capture."
