Stereokenttää

Stereokenttää is a Finnish term that translates to "stereofield" or "stereoscopic field." It is primarily used in the context of stereoscopic photography and videography, referring to the area within the frame where stereoscopic depth is perceived by the viewer. This field is crucial for creating a convincing and comfortable three-dimensional viewing experience.

The effective stereofield is influenced by several factors, including the convergence of the cameras or eyes, the interaxial distance (the separation between the two viewpoints), and the composition of the scene. Objects placed too close to the viewer within the stereofield can cause discomfort or eye strain, a phenomenon known as "stereo window violation." Conversely, objects placed too far beyond the stereofield may appear flat and lack depth.

Achieving a well-defined and comfortable stereofield requires careful planning and execution during shooting and post-production. Photographers and filmmakers often employ specific techniques to manage depth and ensure that the perceived depth remains within acceptable limits for the intended viewing medium. The goal is to create an illusion of depth that is natural and engaging without causing visual fatigue. The concept of the stereofield is fundamental to the art and science of stereoscopy.
