They're a Canberra success story - two talented local kids who grew up in the capital and went on to successful careers shooting glamorous weddings around the world. O'Day, as he told The Canberra Times in 2014, went from Charnwood trolley boy to a speedboat in Monaco, photographing a luxury wedding. Tunney started out part-time but ended up shooting 67 weddings in one year. And All Grown Up is a happy marriage of their skills, though it's a purely professional partnership - Tunney is married and a mum, while O'Day's partner Andrea Rose is one of the six other photographers at the studio.

O'Day says that in the beginning they were fierce rivals. "We'd get a lot of the same couples inquiring between the two of us and we were doing styles of work that complemented each other. We had a very similar clientele," he said. "I'd lose a gig to her all the time and vice versa. And in the competitions, we'd try and knock each other out of the water so it was a bit of a backwards and forwards seesaw."

But as they got to know one another, their relationship changed. Tunney said she and O'Day bonded over photography and a shared sense of humour. "Dan is very charismatic and he's very funny and those traits are still the same today," she said.

"His career moved forward and evolved very quickly and being in the same home town it's been very nice to see him develop. To be part of him developing his career - I can safely say I've helped him get there and equally he's helped me. It seemed like a no brainer to essentially combine our business."

All Grown Up has actually been in business for three years - O'Day set it up after recruiting a couple of other shooters to work for him. He ran the business on his iPad in what little time he had between his other wedding jobs and was all too much.

"Kelly was sitting opposite me, we were sharing a co-op work space and she was seeing the struggle I had to balance everything and she jumped up and said, 'Look do you need a hand?'"

Tunney ended up doing so much of the work that the pair decided they needed to put together a partnership. That was 18 months ago and they have six photographers working with them in Sydney, Melbourne and Canberra.

The glass fronted Braddon studio, on a balcony in the Ori building on Lonsdale Street, is a place to finally call home for their creative talent. O'Day compares it to a record label - all the photographers have a unique hook. "What we're really pushing is individuality," he says. Tunney agrees. "We want these guys to push their own angles, we don't want them to do what Kelly would do or Dan would do," she says.

O'Day says working collaboratively is the best approach. "A lot of people who run businesses, not just photography, they keep their cards close to their chest and it seems automatic for them, they don't want to share. But some of my biggest competitors around the country are also my best friends in the whole world. We've all managed to keep each other accountable for a level of work and professionalism but also keep each other in business with referrals, there's so much more to be gained to be keeping things open minded and being friendly."
