It can and does enhance the quality of your images, most particularly in special occasions like a wedding photo shoot. With the Lensbaby Creative Aperture Disks, points of light (bokeh) in out of focus areas of your photo take on the shape of the center opening of the aperture disk. With the star aperture, for example, points of light behind the subject appear as glowing stars.
You can even shape your own; a company logo, perhaps? Each Lensbaby Creative Aperture Kit contains one f/4 star aperture, one f/4 heart aperture and five blank disks that you can cut into custom shapes. The disks work with the Lensbaby 3G and Lensbaby 2.0 lenses.
