When their respective polarizing axes areat right angles to each other, a "blackout" is producedand when axes are parallel, maximum light is transmit-ted. A visual demonstration of this fact is properly andsimply attained by looking through and rotating twopolarizers as directed. The same effect is transmitted toyour film.

HOW YOUR EDNALITE POLARIZER WORKSThe light coming from the subject being photographed thatpenetrates into your camera lens onto your film to take yourpicture is eally of two parts mixed together. One part ofthis light is true reflected light that gives you the realimage of the picture being photographed. The other part is"glare" or reflected light from shiny surfaces which addsdisturbing light flare to your pictures. Your EdnaLite Polar-izer eliminates this glare or unwanted reflections. YourEdnaLite Polarizer will remove reflections and glare frompictures taken against polished glass surfaces, from water,highly polished furniture, oil paintings and other such glare-producing and light reflecting mediums. Your EdnaLite Polar-izer kills reflections from uncontrolled flash illumination.
