Keep Your Camera Cold
Hints that winter is on the way
falling in parts of Maine tonight provide a not so gentle reminder that it's time to think
about keeping your camera running when you're out there having fun in all of that cold.
Every year about this time an article in some camera magazine tell folks that the way to
do that is to keep their cameras under their jackets and only bring them out to take a
picture. That's partly because camera batteries generally perform less efficiently or not
at all when exposed to freezing temperatures. It's
also partly because the writers of those articles aren't as active as the folks in
northern Maine!
Anyone who snowshoes or cross country
skis knows that when you travel under your own power, you work up a sweat. What do you
think happens to your camera if it's under your jacket with all that moisture? And what do
you suppose happens when a wet camera meets cold winter air?
You cannot avoid exposing a camera
stored beneath your jacket to some moisture if you are an active person. On the wrong day,
that moisture can freeze up your zoom lens, screw up your autofocus or fog up your lens
surface.
An even worse problem might develop if you shove a camera that's been out in freezing
temperatures under a warm jacket or into any other warm place right away. Condensation
collects immediately on the body and the lens outer surface and - worst of all - might
even form on the inside of the lens barrel itself. Little
green things that can etch glass might someday grow on the inside lens surfaces from
moisture trapped in the lens barrel.
So how do you keep your camera going when you're out in winter? It's easy. Just keep your
camera outside your jacket and let it become as cold as the outdoors. Most modern 35mm
cameras will operate just fine, even in sub-zero temperatures, as long as their batteries
continue to provide power. Your focus - pun intended - should be how to keep your
batteries working, not how to keep your camera warm.
Keep Your Batteries Warm
Several
ways exist to do just that. The easiest and cheapest method is to keep a spare set of the
batteries that your camera requires in a pants or shirt pocket. Be sure towipe off any
moisture before you put them in your camera.
You can also
buy batteries that perform better in the cold. Lithium or nicad batteries are available
for many camera models. Lithiums perform better longer in lower temperatures but are one
time use. You can purchase rechargeable AA size nicads that will fit many cameras But no
matter the battery type you use, for the average Maine winter day, keep a spare set warm
and you should be able to shoot when you want to.
If it's really cold, say below zero, I also take the
batteries out of my camera and keep it warm in a pocket until it's needed for shooting.
That method first developed out of necessity while on a six mile hike in 20 below
zero weather in Baxter State Park - gives you two chances to keep your camera going.
And if your camera dies because the batteries got
too cold? Take them out and warm them up in your pocket. Or if you have a camera that has
only a tiny battery to operate it, you can sometimes warm that battery up by rubbing it
between your hands for a few minutes.
When You're Done
You should always bring your camera up to temperature
gradually when you come in form the cold. If you're getting in a car, at the very least
put your camera gear in the back seat and cover it with something to protect it from the
heater. I put my cameras inside a waterproof
plastic case so that they're not exposed to condensation as they warm up gradually. A
tightly sealed plastic trash bag works just as well, by collecting condensation on the
outside of the bag.
Next we'll review how to get great exposures despite
all of that snow that's trying to fool your camera's meter. Then you'll be ready for a
White Christmas. Until then, catch yours in the good light.
