Abstract
A method and apparatus for enhancing a holographic image in order to create an eerie spiritual visual image which can be used in conjunction with religious pictures in hologram form or an eerie visual image of decorative scenes for home or office furnishing purposes or Halloween or other scary situations. A holographic film incorporating an image therein is placed between two plates of optically transparent material such as glass. A direct source of illumination of the image through candlelight set at the focal point distance in front of the hologram film, within its focal plane and at a location no lower than the lowermost point of the holographic image creates the enhanced image and eerie effect in a dark room.
