During a Recent Holographic Sitting

 

 

 

 

Having a commissioned hologram made is very similar
to having photographic work done in a professional
studio. First the subject is prepared and style,
posing, composition, props, etc., considerations are
discussed between the client and the holographer.


Next the subject is posed or arranged in front of the
camera and a master holographic plate is loaded.
(see diagram #1) Unlike a normal photographic setting
where the photographer would take the photograph
with a camera which holds the light sensitive film,
in a holographic studio one needs to envision
the whole studio room as the camera. As such, the
holographic plates we use are sensitive only to
green light and so, prior to shooting, the room must be
darkened and illuminated only under red light conditions.

         1. Loading The Master

Stage 1: The subject or model to be holographed is
placed on the red stool in front of the camera.
Illumination of the subject is verified by using the
lasers pilot mode. When a satisfactory illumination
has been set an unexposed holographic plate (shown
in blue) is then loaded into the main plate-holder.
After proper posing and scene setups and exposure
adjustments are complete the holographic plate is loaded,
the laser is triggered and the exposure is made.
(see diagram #2) This exposure to laser light takes
less than 20 billonths of a second!


Normally the initial setting just described is completed in
30-45 minutes.


Next the master holographic plate is processed and dried.
This usually takes about 1 hour. Now the master
hologram can be veiwed and proofed, but only under
special laser light. This is a very dramatic experience for
most people as the master is like looking through a
window and seeing the whole room exactly as it was at
the time of exposure in TRUE 3/D! After the master
hologram has been proofed and final image planing
considerations have been discussed, the client need not
be present for the rest of the procedure.

         2. Shooting The Master

Stage 2: The control unit is now set for exposure and
when the holographer is ready he simply presses a
button on a small remote control unit to activate the
main flash. Laser light exits from the front two
illumination ports (colored green) and from a rear
reference port to combine at the holographic plate
where a hologram is recorded by interference of the
two beams.
Now the master transmission hologram must be copied
to make the white light reflection hologram that will
ultimately be displayed. This is accomplished by
inserting the master hologram in the transfer rig and
adjusting the virtual 3/D image with respect to how it
will intersect the final reflection copy being made.
(See diagram #3) With some limitations, some of the
subject can project out in front of the final hologram
and some of the subject be displayed behind the plate.


After both holographic plates are loaded and exposure
and image plane adjustments have been set, the laser is
triggered and the final reflection copy holographic plate is
exposed. (See diagram #4)
         3. Aligning The Transfer Image

Stage 3: After the master hologram (shown blue in the
diagram above)
is processed and dried it is inserted into
the transfer rig. The laser is set to pilot mode and a white
screen is placed opposite the master hologram in the
transfer hologram holder. The holographer is able to
align the master hologram by observation of the image
projected onto the screen.
All that is left is for the final reflection copy holographic
plate to be processed and dried. The last step is to
laminate a special black film onto the back of the
hologram to enhance image brightness and viewing.


This whole process can usually be completed the same
day. Your hologram is now ready to be framed and
displayed for all to see and enjoy!

         4. Shooting The Transfer

Stage 4: An unexposed holographic plate (colored
yellow) is inserted in place of the screen. The laser
and control unit are then reset for exposure and the flash
is activated by remote control as before. The hologram
must then be processed and dried after which it is ready
for viewing in white light.
