Iris: A technique used to show an image in only one small round area of the screen. An Iris-Out begins as a pinpoint and then moves outward to reveal the full scene, while an Iris-In moves inward from all sides to leave only a small image on the screen. An iris can be either a transitional device (using the image held as a point of transition) or a way of focusing attention on a specific part of a scene without reducing the scene in size.
