Shinseungback Kimyonghun Memory 2013 digital tablet, custom software and wooden frame 30×24.5×3 cm

Shinseungback Kimyonghun is an artist duo based in Seoul, South Korea. Shin Seung Back studied Computer Science at Yonsei University in Korea and Kim Yong Hun studied Photomedia at Sydney College of the Arts. Together, their artistic practice explores digital technologies related to image processing and computer vision. They are interested in how these shifts and changes in technology have been affecting our relationships with images.

Their work Memory consists of a digital tablet inside a picture frame. The frame includes mountboard that hides the edges of the tablet, but has a small hole at the top for the tablet’s internal camera. Inside the frame is a blurry portrait.

The tablet is loaded with software that detects viewers’ faces. Every time it registers a person looking at it, it takes a photograph of the viewer and superimposes it onto the previous portrait. The software then averages the images together. The face in the frame becomes a composite portrait of all the people who have looked at it.


  • Make a version of Memory for your class group. You could do this in a number of ways. You could set up a photo booth, and photograph each member of your class in the same way and at the same scale (you might want to use markings in the camera viewfinder, and make sure the camera doesn’t move). In photoshop, make an ‘average’ of all of your photographs. There are a number of ways to do this. See if you can work out the most effective way. Once you have succeeded, try making an average photo of the students in another class. How about your whole school?
