Sunsets
Near the summer solstice the sun sets behind the windmill. Four minutes after sunset at ground level its rays still shine onto the clouds steeping them orange, red and crimson. To reach these clouds the rays have followed long curved paths tens of miles long through the lower atmosphere. During the journey, tiny dust particles and air molecules have scattered much light out of the direct beams. Blue light is scattered much more strongly than the longer wavelength red leaving the residual light illumating the clouds deeply reddened.    June 25th 2003 1/70s f/2.8 100 ISO equiv. 280mm efl.
