‘Under the surface of images’ is a phrase used by Michel Foucault in the book Discipline and Punish when referring to the means in which Surveillance is implicated in the discipline, regulation, and normalisation of the body. Here in this paper is used to understand what can be unveil by low-tech images from two different situations: the first concerns Jazmine Headley’s case that had happen in the United States in 2018. The second is related with my practice as an artist and the use of handheld devices in my live performance This is a Low-Tech Movie. In the paper I propose to discuss the use of technology devices as tools for visibility and emotional memory imprint – as described by the neuroscientist Boris Cyrulnik – and how this knowledge can be used in performance practice. The paper is be divided into two main sections, one related to technology and ways of perception, with articles from Jonathan Crary, Camille Barker, and Boris Cyrulnik and, one to the discussion of the concept of 'low-tech image' or 'poor image' produced by handheld devices and developed in my own performance practice.
