"Carnaval de Oruro" was opened at the Arrowtown venue on Friday evening by artist Carlos Biggemann.
The 26-year-old, who is originally from Bolivia, shot the photos on his Canon 5D Mark III camera over three years while attending the annual religious festival which dates back more than 200 years.
Mr Biggemann moved to Dunedin with his parents in 2006 but travels back regularly to the country of his birth.
Around 50 people attended the opening to view the 50-odd pieces which will be on show until March 11.
Pieces include King of the Dark Skin, Earth Angel, The Beast and his Ornamental Horns and The Skeleton with Joy.
"I want to show the people of Arrowtown and want them to enjoy them as much as I enjoyed taking them. They show the contrast, the shapes, the people, the cheering and the jumping — it is all about carnival."
Photography has been a passion since his teenage years when he studied at Aoraki Polytechnic.
In 2013, he won a New Zealand Down Syndrome Association national achievement award for his accomplishments in swimming and photography.
He represented New Zealand at the World Swimming Championships and was an official photographer at the World Special Olympics in Australia in 2013.
Mr Biggemann also won the Stephen Thomas Award, presented by Dame Judi Dench in London, and the NZ National Down Syndrome Achievement award, presented by Sir Jerry Mateparae.
