Composition determines everything — snow and ice.

Snow and ice are both white. If you want your photos to reflect this whiteness, typically, you need to increase the exposure after normal light metering. Without increasing the exposure, snow often appears gray. When shooting snow and ice, it's important to skillfully use the different colors of the sky and surrounding scenery, such as the blue of the sky, the warm yellow or red hues on water or ice surfaces illuminated by sunlight. Different colors evoke different emotions in people.
