A scene is imaged by moving an optical lens relative to an image sensing surface (such as film or a pixel array) synchronously with exposing different portions of the image sensing surface. The synchronous actions are preferably adaptable to the scene being imaged, so objects at different object distances are focused at different times and exposed to different portions of the sensing surface at different times within an exposure frame period. Exposure time for the different portions of the sensor may be varied according to speed or brightness of the different objects in the scene to be imaged, as detected at the camera by measuring apparatus similar to auto focus distance measuring apparatus. A camera and a program of computer readable instructions are also detailed. Alternatives to moving the lens relative to the image sensing surface include changing a shape of the lens.
