Radial blur mimics this same effect in Photoshop.įirst of all, you want to decide what you want to blur. Think of your camera being placed at the centre of a spinning turntable. But, it will circularly distort your image. The Radial Blur filter also deals with a directional blurring effect. The Motion Blur filter is usually grouped with the Radial Blur filter on Photoshop. This means that the filter will distort the subject to suggest the camera is moving past in a swift motion. The Motion Blur filter is for a directional blurring effect. Photoshop’s blur filters all work in unique ways. How is Motion Blur Different from Others? Plus, the contrast between the blurred parts and the still parts can make the subject look even sharper. It helps indicate movement or the direction the subject is moving in. The camera sensor records how you move light, therefore recording a motion trail.Īdding a motion blur filter can dramatically change the image. It’s most noticeable with light painting. This process can be made clear by taking photos at night. The result consists of faded and blurry areas in your picture of where your subject has moved. As the subject moves in the frame, the camera sensor records the subject’s movement. So, motion blur is caused by a subject moving faster than the camera’s shutter speed. In portraits, people had to stay as still as they could not to cause a blur. Before we had the capabilities of a fast shutter, everything would have to be still in the image to be sharp.
