A method of varying focus in a scene. Specifically, one embodiment of the present invention discloses a method for modeling a scene using a parametric texture map (PTM) under varying focus conditions of one or more dimensions: e.g., focus depth and depth of field. A dataset of photographs is obtained under separate focus conditions. Approximation of the dataset creates an associated PTM representation that is capable of generating scenes of the photographic scene under varying focus conditions anywhere within the range of focus conditions specified by the initial data set. In addition, extrapolation yields results outside the range of focus conditions.
