Diffracting Digital Images in the Making [PDF]
Visual Resources, 2021 This paper presents a diffractive dialogue between ethnographic accounts of imagery, digital or computational imaging, and art and archaeology practices. It develops the notion of images in the making in the context of the digital domain, to discuss what an image is and can be today.
