PHOTOGRAPHERS,
LIKE INSECTS, are attracted to light.
Our eyes seek it all the time.
Just like
those six-legged creatures, however, too
much of a good thing can overload our visual sensors. When this happens — Zap!
Snow is the photo-graphic equivalent of the insect-beckoning porch
light or electronic bug
trap. Light, which is contained in winter snow, keeps photographers
forever striving to balance its potential for exposing texture and
details against the dangers of blinding overexposure. For people
who want to walk that
line, here are a few
tricks for capturing the
best of the season on chrome, print film or
digital formats.
White light fever
Snow,
for starters, is frozen water. To the camera, snow is a translucent
mirror-like expanse that reflects the ambient light. In the midday
sun, snow appears to be bright white. If you look beyond the surface
to discern what the camera sees, you'll notice that snow
has the amazing capability of taking on almost any colour. This
phenomenon is most apparent at sunset or sunrise when the sky's
pastel tones on the surface snow fire off glittering prisms. A photographer
can exploit these characteristics to wonderful effect, as in this
photo (left) taken at Lake Louise, where
I captured the red-hot lamps of a midnight torchlit parade reflecting
on the icy contours of the trail.
Snow
blind bind
If I can't control the amount of snow without changing an image's
impact, I sometimes go big with the snowy background and rely on compositional
techniques to define its expanse. In the opening picture of L.P. Segal
(top), the angle of the image allowed me to capture the reflected blue
of the sky on the snow, while the late-afternoon shadows reduced any
white glare in the halo, allowing the viewer to focus on the skier.
My fill-in flash caught the middle of his goggles, thereby illuminating
the visor and clearing shadows from his face. When you are dealing
with a snow-covered landscape, it doesn't hurt to photograph
subjects in bright colours.

Meter made
Even if you have the most expensive camera on Earth, through-the-lens
(a.k.a. TTL) metering is programmed to turn everything grey, including
the whitest snow. You can easily circumvent this function by either
using a Kodak Gray Card during the exposure or manually overriding
your meter. I typically take the latter approach, shooting between
one and one-and-a-half stops over my camera's reading.
For example, an exposure of 1/125 at ƒ8 could be taken at 1/125 ƒ5.6.
Just don't forget to change your light meter back to zero after
shooting. Another option is to set your TTL system to the spot-metering
function and direct the focal point at something that is a neutral
colour, like a tree trunk or rock. Once you've taken the reading,
refocus on your subject.
Photo sensitive
Another way of
controlling the amount of light in a photograph is to reduce the
quantity of snow. This enables the viewer to catch the
winter context of the shot without being blinded by it. The shot
of L.P. Segal cliff jumping (right) is a good
example. While the background is almost
completely neutral grey, the skier's own shadow on the snow below
him gives
context, breaks the monotony of the snow and adds a sense of motion.
The cool colour of the background is also easy on the eye.

Dress up!
Patience is synonymous with comfort and warm, dry hands and feet.
Dress
appropriately, even if you look goofy — at
least your pictures won't. I tie my gloves together with
a string through the arms of my jacket. An extra pair of stretchy
gloves under your snow gloves or mitts are excellent for manoeuvring
lenses without exposing your fingers. If you can't create
a fit that works, Helly Hansen and Wind River make such combos.
Bag it!
Bring a plastic zipper bag to protect your camera from
the killer condensation caused by drastic temperature shifts.
When moving cameras from cold to warm, capture cold air from
outside with your gear, seal the bag and let it warm slowly to
avoid condensation. Pocket it!
The deep-freeze saps batteries and causes film to
break. Pack extras of both in an inside pocket. Automatic
cameras can also run into trouble at extreme cold temperatures
(–30 to –60 Celsius degrees). A manual
camera powered by a stock of environmentally friendly
rechargeable
nickel-metal hydride batteries is an option. In general,
a camera chest-pack, such as the Lowepro design, allows
you instant
access
to your camera and offers superb protection. Forget it!
Lenses, like ice, are made from crystals that expand and shrink
with
the weather. Below –30 Celsius degrees,
they can crack. Forget about taking photos
in the deep cold. A buddy of mine had a $10,000 lens crack atop
Mont-Tremblant last year. That hurt! Protect it!
Rewind your rolls indoors after the camera returns to room
temperature. Brutal cold can create what's called
static streaking — cracks in the emulsion of your film.
If you have no other choice, however, just remember to be slow
and steady if your camera is manual, and cross your fingers if
it's automatic. |
