An amateur photographer responsible for some of the most striking pictures taken on Bloody Sunday said he would not have taken them had he known their content.
Mr Robert White - who was 36 at the time of Bloody Sunday - said he took pictures automatically without stopping to study the detail of what was happening.
Mr White told the Saville Inquiry into the January 1972 deaths it was only on the day following Bloody Sunday that he realised he had photographed at least one victim moments after he was shot.
The witness's picture of teenager Mr Hugh Gilmore, running for cover as he clutched his gut, was taken seconds after the youth was shot and moments before he died.
The picture has been used extensively as evidence at the Bloody Sunday Inquiry.
Another picture taken by the witness showed victim Mr Bernard McGuigan taking cover. Previous witnesses have told the investigation that, moments later, Mr McGuigan moved from his place of cover to aid another victim but was shot dead before he could reach the man.
Mr White told the inquiry that he himself became a target.
While taking cover from the shooting, the witness said he looked towards the positions held by British paratroopers and saw a soldier point a rifle in his direction. He dropped to the ground and instantly heard the "whine" of a bullet passing over his head.
"I have no doubt that had I been standing up, I would have been killed," Mr White said.
The witness said he went to stand up or poke his camera out but another man taking cover beside him shouted: "Stay down you stupid bastard, they are shooting at you."
Mr White said he was approached after Bloody Sunday and asked to destroy two pictures of riots in case they were used to incriminate those involved. He said he destroyed four of the pictures.
