Rita Dibert believes in teaching her students art history the hands-on way.
The senior lecturer in photography at Whanganui UCOL teaches her students about long-forgotten methods in photography by making them do it.
Her third-year students, along with photographers from all around the world, are taking part in an exhibition called Alternatives at the Edith Gallery.
As the exhibition name suggests, these are no ordinary photographs.
"These are the processes that were used in the 1850s to 1920s," Ms Dibert said.
