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. Sophie, who is now two years old, was fitted with a prosthetic eye earlier this year.
