Exposure Compensation for Snow
If you have ever attempted to photograph snow, you might notice that your photos usually come out dark and grayish. This is a common occurrence due to the camera’s inability to distinguish snow from overexposure due to light. This is why you will see that your images come out darker, even in dim light or on overcast days. No worries! The easiest way is to adjust your camera’s exposure compensation setting is by adding +1.
If you would like to do this manually, or your camera does not provide an exposure compensation setting, you can adjust the exposure in the Manual exposure mode of your camera by modifying the ISO speed, the aperture, or the shutter speed, depending on the scene you want to capture.
Alternatively, shooting snow pictures in the RAW image format can give you a greater advantage, since you can adjust the settings afterward on your computer instead of tinkering with the camera settings while taking pictures. You will also appreciate the fact that you can do this in the comfort and warmth of your home, instead of spending extra time outside. This is especially helpful when the winter weather gets rough.
Also consider tweaking the different metering modes provided in the camera - like the spot metering, partial metering, or center-weighted average - and evaluative metering that determines exposure according to the AutoFocus (AF) point, even if it is off-center.
