1. A method for more accurately conveying depth in an image, comprising the steps of: (a) displaying an image to a viewer on a large depth of focus display; (b) determining an accommodation for an eye of the viewer who is watching the image on the large depth of focus display; and (c) displaying an image having an apparent focus plane that tracks the accommodation of the viewer, so that as the accommodation of the viewer watching the large depth of focus display changes, the image that is displayed is changed to more accurately convey depth in the image that is displayed.
