Allan Johnston used his made-to-order large-format camera to photograph local vineyards from unusual perspectives for his exhibition titled "Central Otago Wine and Vine for Cure Kids".
Amisfield Wine Company, near Lake Hayes, hosts the free display until the end of October.
The photographs are numbered and dated prints, from open editions.
One piece, titled Ship Creek, is up for silent auction and has a reserve price of $2250. It would normally sell for $4700.
"I've had one family member pass away at a young age because of leukaemia and I'd hate to see it happen again. It's absolutely devastating for the family," Mr Johnston said.
"Cure Kids funds research to prevent terminal illnesses and I thought it was a good cause. Any profit after the costs goes to them, which will be the major part of the monies."
Several Wakatipu businesses have pulled together in support of the charitable event.
Consultancy firm Art Bay co-ordinated the exhibition and set the prices, which start from $750.
Alpine Choppers gave Mr Johnston and his heavy camera equipment a lift to shoot specifically for the exhibition over the past nine months.
Kelp Design spruced up the images by removing dust in an expensive and time-consuming process, then Gray Studios framed all the pieces at cost.
Mr Johnston said the film photographs ranged in size from over a metre wide to more than 2.5m high.
The artworks have crystal clear clarity thanks to his special camera, Nikon lenses and oil-based ink on acid-free paper.
"Those who know wine will know the properties in the photographs but most people will not have seen them from these angles."
Mr Johnston was given his first camera, an Afga 120, by his mother when he was 7 years old in Auckland.
He was surrounded by photography growing up, thanks to his talented uncle John and aunt Wendy Rykenberg, who owned a photography studio in central Auckland for 50 years.
Mr Johnston's pictures of racing yachts in action were first published in New Zealand Outdoor magazine in 1983 and his career took him to Southern California and Vietnam.
He worked as a part-time assistant for famous American photographer Jim Krantz in Omaha, Nebraska, in 1988 and described him as "an absolute master", with whom he is still in touch.
"I learned so much from him - how to use large-format film cameras and how to build a shot. It's the building of elements into a shot. Nothing's random.
"The other thing was to slow down, think about the shot you want and how you're going to create it."
