Searching for the Unseen Light
For years I have relished in
the gritty beauty of Infrared film. The
images contain a heavenly glow of exposure
from a spectrum that the eyes cannot see. Human
vision is sensitive to about the wavelength
of 700 nm. Infrared film may capture
energy up to 900nm, 200 nm beyond what we
see.
The moodiness of these beautiful glowing
secret images, never seen before by man,
is the attraction of the Infrared photo. The
efforts required to complete a good Infrared
film image is high, however. The film
must be kept refrigerated, it must be loaded
into a Infrared safe transport system camera
(one without internal led sprocket reading
transport systems) in total darkness, kept
cool and out of excessive heat while shooting
in the field, unloaded in total darkness
(which usually means only one roll a day
may be loaded and exposed), and handled and
processed with special regard by the lab. To
give emphasis to the spectral response of
the film a red filter #25, #29 or the totally
opaque #87 must be used. These filters
may be purchased or ordered from pictureline
for the size of your lens. Obviously
the difficulty of using an opaque filter
cannot be overstated, since you cannot see
the subject through the lens at the time
of exposure. Despite all of the inconveniences,
photographers continue to use the film for
the image it produces.
Most digital cameras cannot see or sense
Infrared because of an internal IR (infrared)
blocking filter. To test to see if
your camera is capable of recording IR, point
the TV remote into the camera lens, push
a button on the remote and observe the LCD
screen of a digital point and shoot or take
a picture with a digital SLR and review. If
you see or record a glowing white dot from
the remote then your camera is capable of
IR photos. If you do not see or record
a white dot more camera attention is required. If
your camera can sense IR, compose your image
and place a #87 filter over the lens and
have fun.
Well, if you are attracted to the look,
but put off by the incredible hassle or your
camera cannot sense Infrared, your time has
come. Check out www.irdigital.net for
the requirements of having a digital camera
permanently modified for Infrared use. The
camera surgery removes the IR blocking filter
and replaces it with an internal #87 filter
for about $350.00 plus your camera body. This
is a huge advantage, since the filter is
installed below the viewing system of the
camera. You can freely see through
the camera at all times yet IR images are
captured without all of the attendant hardware
hassles.
The moody look is almost identical to that
produced from Infrared film. The skies
are black and the trees glow with beauty
and majesty. Skin glows. The
film grain is not exactly the same as digital
artifacts, but digital editing can replace
the grain exactly.
If you have been searching for a way to
expedite the IR experience this is for you. This
is just another way for you to enjoy the
beauty of your photography.
