Interferometry - a half silvered mirror.

Duplex takes a chance with the opportunity of exhibiting together. Rather than two individual hangs in the same gallery, we formed the idea of works interfering with each other in order to foreground the idea of relationship. It resulted in a sort of ‘play till someone gets hurt’, but also in the potential to create a new and expanded reading of our works.

Interferometry is an interesting technique that uses light to measure distance. It employs a half silvered mirror to split a single beam of coherent light in two beams that travel along separate paths. When these two beams are recombined (superimposed), a relative constructive or destructive interference occurs - an adding to or subtracting from each other that results in lightness or darkness. But what does this have to do with this exhibition?

Betty’s notions of the catalogue, the scientific and historical listing and dissection of knowledge into orders, especially botanical, and Greg’s tendency toward a more iconoclastic endeavour, would seem at first to have little in common. But we do share a long standing couple relationship. We live and work together in somewhat compromised home studios at opposite ends of a house in Torrensville. So there should be something going on! Some leakage, some evidence of relationship, a something of one in the other.

What part do our relationships play? We sign our works but are they entirely autonomous? And what play of influence and originality occur in the things we all make?
