Apply the Iris Shot effect using a sharply defined circular viewing aperture surrounded by opaque black masking. Center the opening on the existing focal subject, leaving its important features visible while obscuring outer corners. Add subtle monochrome film grain and a slightly softened aperture rim. Keep the original subject and composition.
A[circular section]of the image [opens or closes].
Principle
A[moving mask1increasingly obscures the edges]of the image.
Example
The Magnificent Ambersons, 1942.
Try it out
Focus on an important detail instead of the center of the image.
Background
In the silent film era, the iris2drew attention to faces or concluded scenes. Orson Welles revived this historical form in 1942 in *The Magnificent Ambersons*. Columbia Pictures explicitly includes rectangular, triangular, and diamond-shaped masks in its design palette. The attribution to the early 20th century indicates widespread use, not aclaim of sole invention.
Distinction
The iris diaphragm as avisible image mask is not the same as stopping down the lens. An iris can also have shapes other than acircle.
Aftermath
Apicture border can shape action and attention.

Not necessary. It initially reduces the visible image area.
