Uta Barth is an artist whose photographs explore the nature of vision. She tries to show the difference between how a human sees reality and how a camera records it. She also examines visual perception and how the incidental and atmospheric can become subject matter in and of themselves. In many of her photographs, Barth tries to focus the viewer's attention on the process of perception through the depiction of incidental objects that are in nondescript surroundings. Throughout some of Barth's series, she investigates both literal and metaphorical aspects of perception by trying to capture the image one keeps after turning away from an object.
Uta Barth is known to not care at what her camera is pointed at but more interested in what is seen through the lens. Barth is most known for her series Ground and Field, which is a series of photographic blurs which were caused by focusing the camera on an unoccupied foreground. These photographs test the connection between the descriptive clarity of photography and the haze of one's memories. One of Barth's newest series is focused around the moment when light begins to transition and fade. This series, Sundial, are a collection of photographs that operate between negative and positive, shadow and light, and visibility and invisibility.
