At slow shutter speeds, snowflakes become streaks, a look you can use to your advantage. At exposures of 1 sec or more, you will get very long light streaks—or no trace of snow at all, depending on the weather and the brightness and texture of the background. I’ve shot photos during moderate storms in which it was hard to tell the snow was falling without enlarging the image many times.
Still, I prefer snowflakes to appear as dots rather than streaks—frozen in flight rather than blurred. A shutter speed of 1/250 sec usually does the trick; closer to 1/500 sec may be better for very fast-moving flakes. (Shutter speeds above that won’t make a difference.) Faster shutter speeds also allow you to shoot your camera handheld, which is more practical than using a tripod in foul weather. I do use a tripod on occasion—for instance for my photo of the flowing stream (first photo in the gallery).
Keep in mind that the spotmeter in your camera gives an exposure reading to render a subject a midtone. So if you meter off the snow itself, you’ll end up with an underexposed image (and gray snow). I usually manually spotmeter the snow and add about 1.5 stops of additional exposure.
With your camera set to centerweighted or evaluative metering, you can often get away with shooting on autoexposure, but take test shots to determine how much exposure compensation to add. The most accurate way to do this is to check the histogram. Make sure that the graph is pushed toward the high- light end of the scale (right-hand side), but does not spill over the edge, which indicates clipping of the highlights.
But shooting in fiat light can give you a muddy result, even with proper exposure. You can use the Levels tool in Adobe Photoshop or Photoshop Elements to spread the tonal range and bring back some life to most shots. If you need more contrast, use the Curves tool or the Brightness/Contrast sliders. You may even want to add a little color saturation with Hue/Saturation, but don’t overdo it. (See How To: Work with Curves for a primer on color and contrast.)
Pick Your Gear:
Focal length also affects the appearance of falling snow: With long lenses, you generally shoot through more snow because of the greater distance to the subject, creating a fine texture- screen effect. A wide-angle lens, which usually necessitates a closer proximity to your main subject, means you’ll get fewer flakes between your camera and subject—but more of them may be in focus due to increased depth of field.
So shoot more than one version of the same scene, and try different focal lengths, so you can choose an image that has the best snowflake effect. And be sure to take several frames of the same version, as a large snowflake close to the lens can obscure important detail—I learned this the hard way.
A zoom not only gives you this flexibility but it saves you from having to go inside to change lenses—a must to protect your camera from moisture. It also pays to use cameras and lenses with plenty of weathersealing, and to always use your lenshood and UV or skylight filter to protect the front element, as well as an umbrella to shield your gear.
Even better, stay in your car, if possible, and shoot with the window rolled down. Why get colder than you have to?
