Mary - it's actually not as blue on my high resolution monitor, but I think it has something to do with the blue sky and white white snow. I have a nice camera, but I don't know a whole lot about how it works. I generally just shoot & hope for the best. The smooth area is our pond, all frozen over.
Very nice, curlykate! We were just out walking the dogs in the fresh fluffy 6 inches we got this afternoon and evening. Thank goodness we're not having the bitter cold that some of the country is getting, it was a beautiful walk!
