Snow scenes can be awkward to photograph. If you've ever taken a shot of a lovely bright snow scene only to be disappointed with a dull, lifeless, result you'll know what I mean.
What happens is under-exposure. The camera's metering system assesses the scene, decides it's far too bright and, assuming you don't want all that light in your image it sets about keeping some of it out. It can do this by setting a smaller aperture, a faster shutter speed, a lower ISO or a combination of all of these parameters. For the majority of pictures in good weather this is exactly what you need, but for snow scenes (and some bright beach scenes) it definitely is not what you need.
How to overcome this problem? It depends on your camera, but it's relatively easy:
- If you have a compact, point-and-shoot camera set to Auto mode, you can use something mid-toned (i.e. darker than the snow) to set your exposure. Before composing your picture in the viewfinder or on the LCD screen, simply point the camera at, say, a road (if it's not covered in snow) or your own hand or any other mid-toned object as long as you fill the frame with it. Then press the shutter half way down and hold it there. Recompose the image with your chosen subject while still holding the shutter half way down, then press it the rest of the way down to take the picture. For most compact cameras, holding the shutter half way down locks the exposure settings.
- For cameras with more control, such as (D)SLRs, I'd advise selecting aperture priority mode first and setting the exposure compensation to at least +1 stop and possibly +2. Then compose and take your picture as normal. You may have to experiment with the amount of exposure compensation that you set for the results you prefer.
