I had an opportunity to discuss the show with my supervisor, and she encouraged me to see it as an opportunity to show my work, not as documentation but as art in it's own right.
So the show was stripped down to a minimum. I showed a film, an object from the film on a specially made shelf and a photograph. I felt very exposed, but the response I got from visitors was very positive.
Most people got what the film was trying to communicate, and we had some interesting discussions about memories and sites. And better still, the pauses between visitors gave me lots of time to contemplate the work and to think about how it fits in to my original proposal, and how it moves the work forward.
