Modulation

The Parameter-Image

    • 98 Pages

    Modulation: The Parameter-Image offers a new way to understand what images are and how they work. Instead of treating pictures as fixed representations of the world, this book argues that every image is a field of variation—something continuously adjusted, tuned and transformed. From the mechanical instruments of the Renaissance to today’s generative AI, images have always been shaped by certain parameters: brightness and contrast, scale and resolution, signal and noise. Modulation, the art of varying within limits, is the deep logic behind all imaging.

    Tracing this idea across mechanical, optical, electrical, electronic and algorithmic media, the book shows how images emerge not as single artefacts but as dynamic processes. It links the sliders of photo-editing software to the vanishing points of perspective drawing, the tuning of radio signals and the latent spaces of machine learning. Each chapter demonstrates how cultures of modulation have organised the visible—technically, aesthetically and politically.

    Drawing on philosophy, media archaeology and art history, this volume reinterprets thinkers such as Gilbert Simondon to propose a theory of the ‘parameter-image’: an image defined by its range of possible variations rather than its fixed form. Written by a scholar whose background bridges philosophy, media theory and visual culture, it offers both conceptual clarity and historical depth. It will appeal to readers in media and cultural studies, art and design, philosophy and aesthetics and anyone interested in how images—past and present—are made to move, vary and think.

    Modulation rewrites the history of technologies from brick-making to triodes and aesthetic history from printing to synthesisers, tracking the tension between quantities measured in units and the continuum of intensity. Dvořák’s speculative archaeology is the generative principle of perpetually evolving technical and visual artefacts. Illuminated with brilliant insights into print-making, light switches and AI, Modulation changes your ideas with the idea of change.

    Modulation simultaneosly summarizes and reorients the best of what media archaology has had to offer over the past 30 years. We thought communication was all about switches. It is in fact much more about knobs. We needed Tomas Dvorak's sharp and crystal clear writing to realize the central role played by modulation throughout history, from the pantograph to generative AI. No clearer insight is currently available to grasp the technopolitical implications of the 'latent spaces' of today's Large Language Models. A truly important, and most pleasurable, read!
