Artist In Residence Program
Non Holographic Artists:
For those unfamiliar with the holographic process, some clarification
may be required. As for general information it is suggested that a
search under holography should yield a wealth of information. A good
beginning might be: Wikipedia: Introduction to holography
As for
the particular distinction between traditional holography and 'pulse
mastering', it refers to the specific type laser that is used to
record the original image. Most holograms are made with a continuously
lasing system where the vibration isolation requirements make
any movement of the subject critical. Normal body functions such
as skin moisture evaporation, heartbeat and the like make portraiture,
in particular, impossible. Even solid inanimate subjects recorded
over exposure times often in excess of many seconds may run the
risk of moving during exposures . Unlike photography which might
record a blurred image, the holographic recording will likely record
absolutely nothing. This restriction is what often daunts many artist
in participating in the making of holograms.
The 'pulse laser', on the other hand, renders exposure times
in billionths of a second and therefore, similar to high speed photography this freezes any movement in the three dimensional
space.
Of further note to Artists unfamiliar with the technology,
this 'master' hologram is a laser viewable hologram. It is customary
for artists to follow this mastering session with a 'transfer' session
which essentially involves making a second hologram of the master
in order to make it viewable with a more readily available white
light source. This transfer session is traditionally done using
continuous wave laser systems, and by nature often takes more time
to accomplish, in terms of both exposure and overall setup time.
For this reason, the pulse master session can take a day or two to execute
while the transfer will take longer. Under the guidelines it
should be noted that the awards do provide time to accomplish this
session and of course a technician will be provided.
The transfer session will yield a white light viewable hologram
of the intended imagery. Generally, this transfer will yield a reflection
type holographic image, traditionally , a monochromatic holographic
image with a depth with maximum clarity over several inches behind
and in front of the holographic film. In some cases, the transfer
could be made in a transmission mode, allowing for greater scene
depth but with a sacrifice in vertical parallax. This 'rainbow'
transfer will result in a hologram which will shift in color as
the viewer changes vertical viewpoint .
Though all this may sound quite complicated, be reminded
that all awardees will be carefully guided through the process every
step of the way, and it is hoped will subsequently understand the
basics of the process .
