It's literally a developing story: Snap shots of a stunning young bride and groom from a bygone decade.
Eyes to the camera, both smiling, her gloved hands holding a traditional bouquet, and he donning a lovely carnation in a button hole.
Who are they and whereare they now?
The photos were taken by photographer Ian Hulse, who has since died. His son Richard wants to give the couple pictured these precious souvenirs of their special day. But he needs help finding them.
"When my father passed away I inherited his personal archive of private, creative work that he did when he was a professional photographer. It also included a whole lot of family photos - stuff from the 1960s and from the 1970s," Richard told Checkpoint.
"Recently I was looking through these photos for an image of my mother to scan, and I found a little packet of negatives that was somebody's wedding, that was not part of our family.

"He was active from the '50s through to the late '70s, but he was doing weddings I think from the '60s through to possibly the early '70s."

Richard said in earlier decades the negatives would have been about half the frame size.
"These are 6x7cm, so the camera he would have been using to shoot these was probably a Mamiya 6x7 medium format. This type of film known as 120, in the professional trade."
At the top of the packaging it says: "Barr-Carlyle wed".
The couple may be in the 70s or 80s now, Richard said.
"I think they're probably still living. They look young enough in this photo to still be around, so I hope we can actually find either them or their children, because I think family history represented in photographs are so important.
