Motion blur can be adapted in many areas of photography; to create a sense of movement in the image or to blur out the background and bring the viewer’s attention to a certain part/detail of the image.
Side By Side Before vs After Image
Although I used Photoshop to create this image and effect, it’s possible to achieve this using the camera. A way to do this would be slowing down the shutter speed, using a small aperture and decreasing the ISO. These things combined would create a naturally blurred photo with a subject in focus.
Often, in Photography, motion blur adds movement and a lively atmosphere.
