Obverse Change by Anton Halla brings together works centred around an original way of developing photography. By using a frottage process, in which he manually develops images by transferring coloured pencil onto Tyvek through photo etched alpaca steel plates - he builds image through repetition, pressure, friction and contact rather than capture. The exhibition departs from screenshots taken from Mary Poppins (1964), each conspicuously absent of bodies: a doorway, animatronic birds, chalk drawings on pavement. These become pretexts for an inquiry into how images circulate beyond the objects and moments they once depicted — across eBay listings, animation cels, viral phenomena, and commercial memorabilia. A fused animation cel, a Roman Originals dress made famous by a 2015 internet debate over colour perception, and hand-painted popcorn replicas each arrive in the exhibition carrying histories of reproduction and exchange. Throughout, value is negotiated as much through visibility and circulation as through material presence.
