Opening a Window to the Scene
The iris is a transition technique that gets its name from the iris of a camera lens, which opens or closes to let in light. An ‘iris in’ mimics this action to begin a scene. The screen starts as black, and then a small circle opens up in the center, revealing a portion of the scene. This circle then grows outwards until it expands to fill the entire frame, revealing the full shot. It is a highly stylized effect that was a staple of early cinema.
In the silent film era, the iris in served a practical and artistic purpose. It was an elegant way to introduce a new scene, often used to focus the audience’s attention on a specific character or important object before revealing the broader context of the location. This technique guided the viewer’s eye and added a touch of theatrical flair to the beginning of a scene.
A Tool of Nostalgia and Homage
In contemporary filmmaking, the iris in is almost never used for serious dramatic effect. Its heavy association with silent films and classic animation has transformed it into a tool of nostalgia. A modern director might use an iris in to:
- Evoke a Vintage Feel: A film that wants to consciously mimic the style of a bygone era, like The Artist (2011), might use an iris to signal its commitment to the silent film aesthetic.
- Create a Comedic or Cartoonish Effect: The Looney Tunes and other classic cartoons used the iris extensively. Employing it today can give a scene a lighthearted, playful, or self-consciously retro feel.
- Pay Homage: A filmmaker might use the technique as a direct, loving nod to the history of cinema.
Like its counterpart, the iris out, this transition has moved from being a common cinematic tool to a specialized device used to evoke the past.
