"We will be photographing the shadows of these objects to represent what is left behind after memory, meaning or personal value is lost," Smith said.
"We are asking anyone with these kinds of possessions to bring in just one to us at the Geoff Wilson Gallery project space.
"We would like to photograph the shadow of the object while they wait - it will take about 10 minutes, print it and then hang it in our growing exhibition of 'things that have lost their meaning'."
The pair will be available to photograph items between 11am and 2pm on August 30, September 6 and September 13.
The growing collection of shadows on display will be exhibited in the Window Space at the Geoff Wilson Gallery, at NorthTec's Raumanga campus until September 16.
