UPDATE: The humble photographer behind this candid photo is surprised it has reached so many people.
James Day told News Corp Australia he can't believe the response to the photo.
"My Facebook post alone has been seen by over 13 million people right now.
"I've never had anything like this before.
"It's crazy to think that this country boy from Armidale has been able to reach so many people!"
James captured the beautifully raw image at Adrian and Roslyn's wedding on April 30 at Milton Park Estate in Bowral.
He was sitting with Adrian in a chance meeting in Iceland when News Corp spoke to him.
He said he thinks both Adrian and Roslyn are also "very surprised by all the attention".
EARLIER: WEDDING photos. They can be so stilted. So posed.
New South Wales wedding photographer James Day was setting up one of those traditional "grand sunset scenes" when the light "suddenly became amazing".
He went up to the newly wedded couple and told them to stop posing.
"Just enjoy your first sunset together as husband and wife."
In a post on Facebook, James said they then held each other "in the most beautiful way".
"It was so much more beautiful than anything I could ever set up."
Then he turned to the groom, Adrian and said: "I have a question for you, but I want you to tell the answer to Roslyn and not me."
He asked Adrian to tell Roslyn why out of the "billions of people on the planet" he has chosen to spend the rest of his life with her.
Adrian bent his head and started whispering the answer in his new wife's ear.
"In a matter of moments I could start seeing Roslyn's eyes glisten, then the most beautiful tears streamed down her face," James said.
Then James found himself crying.
"Oh Love, You are oh so precious," he wrote on the photo that has since gone viral with more than 57,000 shares, 160,000 likes and almost 10,000 comments.
