Scandinavian Snow by My S95

One difficulty I found out about shooting snow during my visit to Canada was exposure. This time, I did pay much more attention to it so at least not all photos are out. In most circumstances I'll set my S95 to Evaluative Metering Mode. When the sensor is metering for the entire frame, the camera will tend to underexpose as the large bright white areas generally trick the camera into compensating more than necessary. As a result, the snow comes out looking grey. This happens more when it's cloudy and the scene is almost all white. Here are some tips to take note:

Always take the first trial shot and check if the snow appears white or grey.
Watch the histogram on snow shots to make sure that the stack is right up against the right hand side of the display but not past it.
Open up a stop or two to make the snow white and expose the subject properly by adding an exposure compensation of +1 or more, depending on the scene.
Choose to shoot RAW for snow scenes to have more flexibility for exposure control during post-processing.
Temporarily switch to Spot Metering Mode and focus on the subject.
Another option is to meter the sunny sky and recompose to shoot the picture (make use of the AE Lock function if the subject is out of focus after the recomposition).
Use the Snow Scene Mode (SCN -> FUNC).
