Silver Falls State Park is located at about 1,200 ft elevation where the Cascade Foothills meet the edge of the Willamette Valley. At this elevation rain is common but snowfall is a very ephemeral event. On this particular day, I arrived in the morning on slippery roads to find the trees surrounding the waterfall covered with fresh snow. I had to wait for the snow to stop to get good images. At the 1 second exposure used, any falling snow would be registered as distracting streaks through the frame - not the desired effect. The exposure was based on a spotmeter reading on the snow. I then opened up about 1 2/3 stops from that reading to keep the snow white.
