"Search for highlights or contrasts in the lights and the shadows to find interesting photos in ­winter. The sunlight shining through trees or bushes to create shadows on the white snow. Sunlight sparkling on ice. Animal tracks in the snow. The best times for winter photography, like every other time of year, are early morning and at sunset. You get a different glow from the light, it's not as direct. But a bright sunshine on the snow or ice can also lead to some interesting stuff."
