Oak Leaf on Powder

M. Bogen, morning after the snow, January 8, 2016

This is how this iPhone photo came out, with no doctoring. The snow was pure white, of course, but in shadow. So I think this remarkable deep blue was produced by the combination of shadow and reflection from the bright blue sky. Oak trees never lose all their leaves until the winter is over, so this nearly weightless leaf blew over from my neighbor's tree and came to rest on our back patio.
