Prince Philip asked for a photographer to take pictures of his funeral from inside a "hidey-hole" pillar.
Arthur Edwards, 80, had taken photographs of the Duke of Edinburgh for 40 years before he captured his final moments from the fake pillar on Saturday.
The touching pictures were a fitting tribute to Mr Edwards' pal Prince Philip, who he bonded with during his time photographing the royal family for The Sun.
The images show Prince Philip's coffin, which was draped in his standard and other regalia, being carried up the steps outside St George's Chapel at Windsor Castle.
Mr Edwards said: "With a letterbox-shaped slit, it was like the bird-watching hides where Prince Philip spent hours of his retirement at Sandringham.
"When his coffin went past my hidey-hole and into the chapel — my last sight of the man I photographed for 40 years — I was overwhelmed with memories of an incredible man.
"From the most unusual vantage point of my years photographing the royals, I was close enough to see Prince Charles look broken.
"Close to tears, I could see he realised the weight of the task ahead to look after his mother and the monarchy."
Mr Edwards also took a dramatic picture of a member of The Rifles collapsing outside St George's Chapel.
Prince Philip spent more than a decade planning his funeral, designing his Land Rover hearse over a 16-year period.
The vehicle featured an open top rear with special 'stops' to secure the Duke's coffin in place.
He began designing the 4x4 in collaboration with Land Rover in 2003 - and made the final adjustments in 2019.
Prince Philip also specified the music he wanted at his funeral, requesting that the ceremony start with buglers from the Royal Marines sounding the naval call Action Stations.
This was followed by the Archbishop of Canterbury pronouncing the blessing, before four choir members sang the national anthem.
