GENERAL GUIDELINES FOR LIGHTING YOUR HOLOGRAM WITH A SPOTLIGHT

 A hologram needs direct light from a spotlight, shining down onto the hologram. This can be a regular
     60 Watt ceiling spotlight. Use regular clear spotlights only - frosted glass or mirrored front lightbulbs
     will diffuse the light.

     Halogen spotlights are also very suitable for lighting holograms. If you are using halogen light, it is best
     to fit a spotlight with a 20 or 50 Watt bulb with a 12-14 gradient (dispersion).

                                              
     It is usually preferable to hang your hologram so that the centre of the image is at eye-level.

     The light should be shining down onto the hologram under approx. 45 degrees. The distance from the
     spotlight to the hologram should be at least 1 meter (3 ft), preferably 2-3 meter (6-9 ft).

     (If a normal spotlight is too close to the hologram, the image will be unsharp. Using a halogenlight can
     solve this problem.)

     In case you have other spotlights shining onto the same wall, make sure these do not also shine onto
     the hologram, as this might cause double images (ghosting).

     In some situations, the hologram might work better if it is hanging a little bit higher and slightly tilted
     forward. To do this, make a loop of steel wire from the left to the right clip. Adjust the length of the
     wire until it almost reaches the top of the frame. Use this loop to hang the hologram from. Place some
     light object (a matchbox for instance) behind the top of the hologram.

     

     Hanging tilted like this, you can see the hologram from a lower viewpoint further away.

     Holograms look very nice when lit by direct sunlight. You can try this out, but it is advisable not
     to expose your hologram to bright sunlight for more than a couple of minutes, as it might get damaged
     by the heat and the ultra-violet rays.
