If you are experiencing a glare in photos of snow, make sure you aren't using your flash feature. Pictures of snow are more likely to come out gray than to have a glare.
When snow is brightly lit, the camera perceives it as something gray that is being brightly lit rather than something white being reflective. The camera automatically tries to correct this by returning it to the "original" gray color. If you own a digital camera and can adjust the white exposure, this solves the problem. If you can set the white balance by showing the camera a spot that is pure white, that works also. However, with that method, because careful not to choose a shadowed area, because the camera is likely to assume the snow is gray again.
