Jan Evangelista Purkyně was a Czech physiologist who, in the mid-19th century, conducted a series of studies on light and color, which came to the conclusion that the human perception of color depends on the intensity of illumination. Two centuries later, Helena Gouveia Monteiro studies, through artistic creation, the different visual and cultural recognitions engendered in humans by the various perceptions of language and audiovisual experiences. In “Purkyně’s Dusk”, her debut work at Curtas, the artist captures Super 8 footage of a garden in the late afternoon of a summer day, both in color and in black-and-white. This dusk, with a fainter contrast of figures, was later manipulated, in editing, with the use of both digital desaturation and more traditional photochemical processes of photography. Helena Gouveia Monteiro creates an eminently visual experience, reminiscent of the famous Kodak’s “Shirley Cards”, and enhanced by the absence of sound, which challenges the viewer to question their own perception.
