Juliana Hoyos (Manizales, 1992) is a Colombian visual artist whose practice investigates how images come into existence and the conditions that shape how we see them.

Working across photography, moving image, installation, sound, drawing, and writing, she approaches images not as fixed representations but as processes that unfold through observation and encounter. Her interest lies not only in what an image shows, but in everything that precedes and conditions it: the light that makes it possible, the time that transforms it, the tools that shape it, the gaze that interprets it, and the imagination that completes what remains unresolved.

Her works often operate at the threshold between visibility and illegibility. Through altered photographic materials, optical devices, ambiguous moving images, sound, projection, and spatial interventions, she creates situations in which seeing becomes conscious and uncertain. When visual information is incomplete, unstable, or about to disappear, what we see is shaped by memory, interpretation, and imagination. What an image withholds becomes as significant as what it reveals.

In recent years, her research has expanded into scientific imaging, astronomical observation, and contemporary technologies of perception. Drawing on instruments, visual archives, datasets, and systems of observation, she examines how phenomena beyond direct human perception are translated into visual form; and the distance that persists between what exists, what can be measured, and what can be seen.

Influenced by phenomenology, optics, and the epistemology of the image, Hoyos understands perception as neither neutral nor complete. Rather than seeking definitive answers, each project tests a different limit of vision, exploring how reality is continuously constructed between phenomena and the ways we observe them, evidence and interpretation, the visible and the imagined.

She lives and works in Barcelona.
