How to Take Care of Your Camera in Cold Weather

Where I live, it gets cold. Not your “Brrr, I need to put on a sweater” kind of cold, but genuine, bone-chilling, spit-freezes-before-it hits-the-ground, kind of cold. Here in Fairbanks, Alaska, winter temperatures regularly drop far into the negatives, and yearly we suffer through snaps that send the mercury plummeting to -40F (-40C).

You’d think that in such conditions I wouldn’t want to step outside, let alone take photos, but you’d be wrong. Winter light, what few hours there is of it, is absolutely beautiful. That sweet, crisp glow can pull me from the deepest funk, and lure me out with a camera in hand. During many long winter nights, the aurora borealis dances overhead, and that too can draw me from my cozy cabin, into the snowy forest to make images. On the days I made the two images below, it was seriously cold, but that light, yep, that light will get me outside.

To venture out in those temperatures, you’ve got to be prepared. You need the right clothes to stay warm, and you’ve got to make sure your camera equipment is ready too.

Forget about fashion

To shot the aurora during mid-winter in Alaska, you need to dress warm!

You’ve got to dress right. It doesn’t matter what the light is doing, if you get frost-bite on your fingers, and can’t operate the camera. When dressed in my winter-photo clothing, I feel a bit like an onion, wrapped in layer upon layer. From inside to outside my system goes like this: long underwear, fleece or wool sweater and pants, down or synthetic vest, 800 fill down jacket with hood, windproof Thinsulate pants, two pairs of thick wool socks topped by expedition quality winter boots, a musher’s style hat complete with ear flaps, a balaclava or face mask, and thin nimble gloves with a pair of expedition overmitts dangling from wrist straps. Last, I’ll often throw a couple of chemical hand-warmers into my jacket pockets. When temperatures drop to -40F, it’s best not to mess around.

Stay Charged

The fluctuations of electricity mean that a cold battery cannot kick out the same amount of electricity as a warm battery. This means that on a brutally cold day, your camera or flash batteries will last only a small fraction of the time they normally would at room temperature. It’s a problem easily solved by carrying a spare battery or two.

A backup battery will let you swap out the cold, dead one in your camera, but there is a hitch: the spares should not be kept in your camera bag, but in an inside jacket pocket. That way they are warm when they go into the camera. When the dead battery warms back up in your pocket (with the help of the aforementioned chemical hand warmers) it will be ready to use for a while again. I find I can shoot at extremely cold temperatures for the better part of day by cycling two batteries back and forth from my pocket to my camera. Though this will vary a lot, depending on how power-hungry your camera is.

Avoiding Bad Breath

The cold comes with other risks, one in particular, can ruin your day of photography, and that is – watch your breath. I mean it. A mistimed, warm, humid, breath will condense on your lens, resulting in a layer of milky frost on the glass. It doesn’t matter how much money you spend on your lenses, no amount of sharpness will make up for that kind of damage. Wiping at it, usually just smudges it more, and defrosting it inside (see below), can take hours. Watch where you breathe, if you turn your camera around to check lens settings, don’t exhale. I also usually wear a neck gaiter or balaclava that I pull up over my mouth and nose. So with your mouth covered, your breath is directed up, where it frosts on your eyelashes instead of your camera.

This is what happens if you accidentally breathe on your lens during a cold weather shoot.

Lens Caps Exist for a Reason

Breath is the usual culprit of fogged lenses, but when shooting at night, there is always the chance that natural frost will form. To avoid this, use your lens cap when you aren’t shooting. If you are walking from one location to another, taking a break, or searching for a new composition, put the cap back on your lens. When I’m out shooting the aurora at night, my cap is on my lens, even if I’m just walking a short distance to a new shooting location.

Back Indoors

Last, and perhaps most importantly, is the return indoors. You know how on a hot day, your cold beer glass gathers condensation? Ever watched how those drips can form and run down the bottle, pooling in a messy ring on the hard-wood table? Imagine that happening to your camera gear. It can, and it will. When you step back indoors to take a break, warm up, or finish up for the day, place your camera and lenses into an airtight bag.

Ziplocks are good, but I favor light-weight roll-top dry bags like those used by boaters to keep their gear dry. These are tough, reusable, and work like a charm. Once sealed up tight in a ziplock or dry bag, condensation can’t form on your gear. Just let your camera warm up to room temperature before you pull it out.

The cold scares a lot of photographers, and make no mistake, a frigid, mid-winter Alaskan night is nothing to mess around with. But with a few precautions – warm clothes, spare batteries, avoiding frost, and protecting against condensation – you can take advantage of the stellar beauty of crisp, clear, days and nights like this one.
