liikumisblurrit

Liikumisblurrit, often referred to as motion blur, is a visual artifact that occurs when there is rapid movement of the subject or the camera during the capture of a still image or a video frame. This phenomenon results in a streaking or smearing effect within the image, where the moving object appears blurred. The degree of blur is dependent on the speed of the movement and the duration of the exposure time. In photography, a longer exposure time allows more light to reach the sensor, but it also increases the likelihood of motion blur if the subject is moving. Conversely, a faster shutter speed freezes motion, minimizing blur.

In the context of digital imaging and video, liikumisblurrit is a characteristic of the recording process. When a camera's sensor captures a scene, it records the light for a specific period. If an object moves during this period, its image is recorded at multiple points along its path, leading to the perceived blur. While often considered an unwanted artifact, motion blur can also be intentionally used by photographers and filmmakers as a creative tool to convey a sense of speed, dynamism, or to emphasize the movement itself. It can guide the viewer's eye and add an artistic dimension to an image. Understanding and controlling liikumisblurrit is a fundamental aspect of visual media creation.
