Snow on Small Plant Skeleton in Cades Cove

I was standing next to a small stream in Cades Cove in 15 degree weather looking for an interesting subject. Along the stream I found this tiny plant that had caught some of the recent snow fall. I used a telephoto lens with an extension tube attached to my camera. With a sturdy tripod, I positioned the camera so the small stream in the shadow would help define the snow covered plant. I determined my exposure using the sunny 16 rule which states that on a sunny day your exposure will be f- 16 with a shutter speed that matches your ISO. Because I was using an extension tube I had to add one stop more to the exposure.LynnFreeny.com
