This photo taken of Ellen reminds me of a horror movie. She may have been walking and the background is plain. You can’t see her features or any details of who it is. This was my first favorite after the one i took of someone walking out a door and coming up the stairs. Motion blur is a blur of a fast moving object in a still photo. The blur occurs when the image being recorded changes during the recording of a single exposure, either due to rapid movement or long exposure. The shutter speed used to take this photo was 81.0mm.
81 mm would be the focal length. the shutter speed is the length of time it took to make the photo expressed either as a fraction of a second such as 1/8 oe as whole seconds 8″ meaning 8 seconds.
