This video was filmed moments before a Scots gran plunged 50ft down a rockface.
Paramedics say Jean Cran, 67, is lucky to be alive after she plummeted down the beauty spot while trying to take a video for her daughter.
Jean's husband John said she should "probably be dead" and couldn't believe she escaped with a hairline skull fracture, broken wrist and bruising.
The gran-of-five bounced off rocks and landed on her back after slipping at Bracklinn Falls near Callander , Stirlingshire, on Sunday.
The footage shows her standing precariously close to the edge filming the beauty spot.
She fell moments after closing her camera.

Jean's fall sparked an emergency which involved around 80 people and a helicopter. Early on during the three-hour rescue, a mystery hero climbed down the rocks to provide immediate first aid to Jean.
Jean, a former company director, and John, 62, from Airdrie, North Lanarkshire, visited the beauty spot on the Kelty Water as they returned from a trip to Oban.
John said: "We went for a wee walk and Jean went to take a video of the beauty spot to show her daughter but slipped shortly after closing the camera.
"She fell about 30 or 40 feet and she landed on a rock and then she bounced and bounced and bounced over the rocks and finally landed on her back.

"She's extremely lucky and she should probably be dead. I couldn't get down to help her because of the position of the rocks. But, Martin, a tourist like us, was determined to get down to help her.
"He was given a hand by another man to get him down the rocks, which were extremely dangerous."
He added: "I believe Martin kept her alive as he stayed with her for the three hours keeping her calm, which probably stopped a heart- attack. He probably stopped her from moving and causing further damage.
"He did a major service. I thought she was going to die and I thought that was the end."
Bill Rose, Killin Mountain Rescue Secretary said: " We arrived at the scene around 4 o'clock and the lady had just gotten to close and slipped in between the rocks.

"We suspected that the injury was to her lower spine so we brought her up vertically after putting on a vacuum splint to keep her mobilised and attaching her to the stretcher."
Jean's video, taken moments before the accident, shows how close she was to the edge of the rocks and the swirling waters below. Jean, according to her husband, stopped filming "nanoseconds" before falling.
Jean is recovering in the Queen Elizabeth Hospital in Glasgow.
Inspector Jo Jollie from Callendar Police Station said: "We can confirm that at around 3.30pm on Sunday 24th March, a joint agency operation was co-ordinated to assist the safe rescue of a 67 year old woman, who had fallen 50ft from top of Bracklin Falls.
"A number of members of the public also helped with this rescue."
