At the heart of a museum or gallery experience is the exhibitions that are presented for the visitor. Behind each exhibition is a curator responsible for developing the exhibition theme or concept, selecting the items for display and writing the information panels and object labels.
While it's my responsibility to consider the overall offering of exhibitions at MTG (for example, I may request an exhibition on a particular subject), it is the curator's responsibility to then develop this into an exhibition.
Concept development can be approached from a number of different angles. Exhibitions may be aimed at creating an emotional response, challenging conventional ideas, commemorating events, providing information in an accessible way and so on. Each exhibition will have an underlying concept or intent - it is never, or at least should never be, random.
Telling a big story, as we are currently doing with World War 1, requires a lot of discipline by the curator.
There are so many parts of the story, so many individual stories and so many themes and concepts that could be told, it is a challenge to select which are critical to achieve the overall goal.
