Afterimage (2022) is a photographic series that explores shifting perceptions of light, colour, and memory by immersing the viewers in a surreal realm of light, inviting them to experience an alternative reality. “Afterimage” is a term in cognitive psychology to describe what continues to appear in the eyes even after the original visual stimulus has passed or disappeared, as any light that enters the eyes leaves an imprint on the retina, forming an image. The series draws on collective experiences of visual phenomena in order to blur the boundaries between natural and built environments, transforming the space into a new reality synchronized with the passing of time. This series aligns with other works by Gladys which visualize emotions and explore the unconscious.
