Electronic camera filters comprise an electronic display configured for use with a camera system to provide different levels of image filtering, as a neutral density filter, for passage to a camera. The electronic display is programmable so that it may be calibrated to provide different desired filter levels associated with different settings of a camera lens iris, focus, zoom, or light meter measurement. The electronic display may be calibrated manually or by calibration information stored or otherwise downloaded into electronic display memory. The ability to program and calibrate the filter level setting enables the electronic display to be operated in synchrony with the camera lens iris, focus, zoom, or light meter it is calibrated with to provide a desired combined or synergistic optical characteristic. The electronic display may be controlled to provide synchronized operation by the same controller used to control the camera lens iris, focus, and/or or zoom.

Camera lens system filter

A filter for a camera lens including an electronic display configured to couple to an object side of the camera lens and configured to filter an image on an object side of the electronic display for the camera lens. A controller is configured to electrically control the filtering of the electronic display. An input is for receiving a control for controlling the controller.
