Truly blown away by Beau Finley‘s photograph taken in the walkway of the National Gallery of Art and his ability to capture motion blur. Motion blur occurs when the image being documented changes during the recording of a single exposure, from either rapid movement or long exposure. When implementing the element of blur in a photograph, it is valuable to have a thorough understanding of contrast, such as light and dark, and what is static or shows motion within the frame. In Beau’s photo, the array of lights in the background distinctly outline the passerby despite the rapid movement. Thanks for sharing, Beau!
