Abstract: Methods and apparatii are provided that use a photosensitive element that is photosensitive to light within a predetermined range of exposure levels to capture images including exposure levels that are outside of the predetermined range of exposure levels. The photosensitive element is exposed to light from a scene. The light from the scene is fractured into concentrated and residual portions with the concentrated portions being directed to form a pattern of concentrated image elements on the photosensitive element when light from the scene is within a first exposure range with the residual portion of the light being directed to form a residual image when light from the scene is within a second exposure range. The light from the scene is adapted also so that the pattern of concentrated image elements is formed in a predefined pattern of concentrated image areas on the photosensitive element.
