"Actually, flare may sometimes be used advantageously. There is no question in my mind that coated and uncoated lenses yield different image qualities. If an "uncoated" effect is desired with a coated lens, a neutral-density filter, or a piece (or pieces) of optically plane (sic?) glass may be placed before the lens. The uncoated surfaces of these Glasses will produce reflection and scattering of light, and therefore slightly reduce the contrast of the image. Of course, it must be thoroughly understood that the addition of such elements to the optical system will reduce definition." Mark Rabiner
