A photo of a young girl in a nightdress standing beside a bullet-riddled door is one of the most striking images of the Troubles - and it was taken purely by chance.
Irish News photographer Hugh Russell, who believes the photo is "one of the strongest pictures I have ever taken", snapped the girl on a compact camera following a shooting in west Belfast in the 1980s.
The child answered after another photographer knocked on the door.
"She'd a wee nightdress on and there was this big row of bullets right down the door," he said.
"I couldn't get up quickly enough to get the main camera out, so I got the compact camera and just took one picture."
The image is just one of dozens collected in Shooting the Darkness, a book based on the critically acclaimed RTÉ documentary of the same name.
Each photo is accompanied by a short description from the photographer explaining how the image came about.
Hugh's best-known picture - an image of Gerry Conlon leaving the back of the Old Bailey in 1989 after his wrongful conviction for the Guildford pub bombings was overturned - was taken partly thanks to his earlier fame as an Olympic boxer.
Faced with a cordon around the Old Bailey, he met a builder who recognised him and took him to a site opposite the court.
"He got me a paintbrush and he said to me, 'If anybody comes past, just start painting the wall.' I splashed paint on this wall for about five hours - to this day my painting skills are still no good," he said.
Hugh said he managed to get close to the door of the court as Mr Conlon left.
"When Gerry Conlon came out the door, he did the big punch and I took the picture," he said.
"I knew I had pressed the button at the right moment and then, when I processed the film in a darkroom in London, I knew I had a really good picture."
The book includes images from seven renowned photographers: Mr Russell; Trevor Dickson; Paul Faith; Alan Lewis; Stanley Matchett; Martin Nangle and Crispin Rodwell.
Some of the most immediate photos focus on young children, including Mr Lewis's picture of seven-year-old Louie Johnston following his father's coffin in June 1997. Constable David Johnston (30) was one of two RUC community officers shot dead by the IRA just a month before the resumption of the ceasefire.
The book also includes the most famous image of the 1994 IRA ceasefire - Crispin Rodwell's picture of a young boy playing with a ball in front of a wall daubed with the slogan 'Time for Peace'.
"It's really nice to have shot one of the pictures that people call 'iconic', that they recognise, and that has been seen all over the world," he said.
Shooting the Darkness, which was officially launched in Belfast last night, is on sale now.
