A photograph taken at a family wedding may have helped to save the life of an 18-month-old girl.
The flash from the camera showed the tumours behind Sophie's eye
The picture of Sophie Cooke with her twin sister Molly should have showed their sets of blue eyes, but instead Sophie's left eye was completely black.
The light from the flash should have reflected from the back of the eye, but a tumour was blocking the light path and the eye showed up as black.
Days later the family, from Sheffield, discovered she had eye cancer.
She had her eye removed and underwent six months of chemotherapy, but has now been given the all-clear.

He mother Tracey Cooke, who lives with her partner David, said her daughter had never complained throughout the treatment.
She said: "It was devastating. They are my little girls, aren't they, so it was a lot to take in. She was so brave and we were very proud of her."
Sophie, who is now two years old, was fitted with a prosthetic eye earlier this year.
Ms Cooke said: "We are just so glad the photograph was taken that day, as it helped save my daughter's life."
