An iris shot is a cinematic technique that involves a circular mask that opens or closes the frame, creating a spotlight effect on the subject while obscuring the rest of the image. This effect can evoke various emotions and focuses the audience's attention, helping to emphasize key moments or characters in a scene. Often associated with the silent film era, the iris shot became a notable feature of D.W. Griffith's narrative style, enhancing storytelling by controlling what viewers see.
