ABSTRACT
This chapter examines the role of digital visioning technology in the production of optical and spatial effects, focusing on public webcams to discuss various procedural aspects of current digital visioning technology's hardware and software. It explores the principal components of image content and legibility (colour, brightness and shape) through human optical cues. Situated within an historical discussion of art and representation, it compares the consequences of embedding attention-controlling strategies within the image that have historically adapted human optical cues to broader aspects of the image's ability to manipulate visual perception. Drawing upon combined fields of digital geometry, the extrapolation of human optical cues of colour, brightness and shape, and modern image-capture technology, the chapter identifies the complexity of elements at play in the digital city.
