COMPOSITION
Using a fisheye lens requires much more thought and planning about picture composition than does a conventional lens. The lens not only produces wideangle distortion but also exaggerates the relative size of objects to conform to its circular format. Objects near the center appear larger than those at the edges, and they show less optical distortion. The entire field is pushed into the distance and spatial relations are trans- formed. And a slight shift in camera position produces a whole new set of distortions.
