This series of images forms part of the ongoing project Soft Ground, Hard Light, which speculates on a multiscalar spatial ontology of photography emanating from the Arditurri silver mine complex in the Basque Country. Evoking the mountainous massif around Arditurri where silver ore and galena have been extracted since Roman presence in the area, the depicted topographies are, in fact, data transcriptions from atomic force microscopy (AFM) probing the analogue film stock of an early 1930s experiment in 3D cinema, Cine (...) en Relieve, by the Basque cinematographer Teófilo Mingueza. In contrast to optical or electron microscopy, AFM uses a scanning probe to physically touch the specimen, recording its surface undulations at the atomic scale of a nanometre, or a billionth of a metre. As a haptic operation based on direct contact between instrument and sample, between apparatus and referent, AFM is literally a contact print, a ‘blind’ scan that senses not the visual content of the recorded image but ‘feels’ its underlying material substrate of silver nanoparticles within the 35 mm film emulsion. The resulting image assemblies visualize a topography resulting from the intra-action between the silver nanoparticles and the scanning probe as much as its transcription through the particular parameters afforded by the AFM analysis software. Hard Light, Soft Ground was initiated during an artist’s residency at Tabakalera Centre for Contemporary Culture, Donostia-San Sebastián, and is currently in production as part of the wider research project Esper Syndrome: Archaeotopologies of the Image at the Royal College of Art, funded by the AHRC through the London Arts & Humanities Partnership.
