Disclosed are methods and devices for the irises of cameras. A non-mechanical or electro-optical camera iris includes a controlled material that is configured to change from substantially transparent to substantially opaque by changing the state of the controlled material to effectively adjust the size of the central window of the iris. Accordingly, the described electro-optical iris would add little or no additional bulk to a small mobile communication device camera. The controlled material can be electrically controlled or thermally controlled. The controlled material can be a set of separately controllable areas substantially surrounding the central window. The set can have an ordering from outer to inner so that outer separately controllable areas in the set substantially surround inner separately controllable areas in the set. Accordingly, by changing the opacity of the outer area from transparent to opaque, the size of the central window of the adjustable aperture is reduced.
