The challenge in taking pictures of snow is to get the snow, more or less, white. Cameras average exposure to grey, so snow appears grey unless the exposure is overridden. The trick is to overexpose a snow picture.
White on white - now that is a tough one, exposure-wise.
Willoway creek - exposure on this one was easy because the interesting detail is
between the ice and the open water.
Hedge row near a parking lot.
Another exposure challenge - white on white on white.
Snow detail not important here, so I washed it all out.
