 In a diorama illusion, the introduction of the blur cue appears to override this familiar information causing objects to appear miniature and toy-like.A common technique for making an image of a full-size scene resemble an image of a miniature model is to have the image progressively blurred from the center to the top or bottom, simulating the blurring due to the limited DoF of a typical image of a miniature.The blurring can be accomplished either optically or with digital postprocessing.
