An Australian man is in the running to be named the world's best architecture photographer, with two of his photos nominated for a prize at the World Architecture Festival. 
Queensland photographer Christopher Frederick Jones was thrilled when he found out he had two photos shortlisted for the 2015 Arcaid Architectural Photograph of the Year award.
Jones says he is "stoked".
"Was I expecting it? Not at all in an international competition like that," he said.
"There's lots of very good photographers and lots of very good architecture.  
"They did a good job of picking my two best shots, yeah I would agree with them."
Jones entered one photo in each of the four categories; Exteriors, Interiors, Sense of Place and Buildings in Use.
His entries make up 10 pe rcent of the competition; only 20 photos were shortlisted in total. 
For the "Buildings in Use" category, Jones' photograph of Nudgee College in Brisbane scored a nomination. 
The photo, which was commissioned by M3 Architects, features a group of boys who live at the boarding school.
"They were a bit cheeky as models, but we had fun with it, it was a really enjoyable day. With architecture pictures you want to get a human element in it to complement the structures and the space in the image," says Jones.  
In the "Exteriors" category, Jones is nominated for a photograph of Gold Coast Aquatic Centre.
He captured the moment where a lifeguard inspects the tranquil water from above.
Jones says to get the perfect shot he arrived at the pool at the crack of dawn and finished at sunset.
Of all those photographs, he likes the ones with the lifeguard because it gives the tower some scale.
It's been 12 years since Jones began doing photography professionally, but it was a passion of his for a long time before that. 
"It's always been a huge interest for me. 
"I used to work as a landscape architect many years ago and I started bringing my camera there. I love the combination of the two." 
The competition photographs will be exhibited at the World Architecture Festival in Singapore on   November 4-6, and the overall winner will be announced at the final nights' Gala Dinner.
