We are blessed with a frozen landscape that has lasted over a week because of the rain and later snow during the New Year's weekend.
One of my favorite subjects in winter is birch trees covered in snow. The problem is white birch bark against white snow will many times illustrate a blank scene for the viewer.
Remember to work with the snow and birch bark against a blue sky or a black background.
Using this technique, the viewer can experience what you saw in the field.
Try to always shoot white subjects against the sun or using side lighting. This technique will cause the black in the scene to snap off the background. Use your compensation dial or overexpose for the right effect.
Have fun and wear plenty of clothes. It is hard to be creative when you can not feel your feet.
