This article has been a long time coming but it is finally available in online form in Leonardo’s Just Accepted (and on my Academia page). Nano-Optical Image-Making: Morphologies, Devices, Speculations ABSTRACT This article provides a technical overview of nano-optical image-making produced between the author, engineering scientists at the Ciber Lab in Vancouver, and the artists Christine Davis and Scott Lyall. It situates the work in relation to other optical technologies like holographs, to the primary application of nano-optical images as authentication devices, and to other artistic practices interested in nanoscale interactions of light and matter. The paper articulates the convergence of visual technologies and designed materials by explaining how the principles of structural color can be used for the production of images. Building a discussion on the shift from device to medium that is anchored around questions of remediation and reproducibility, it concludes with a speculation on informatic matters, or the convergence of mediating functions at the surface of things.
