A worm's eye view of a cloudy sky with a white contrail streak diagonally heading downward from the right-side. The contrail is pure white with dark clouds around it by the bottom corner of the photo, near it the clouds start to appear lighter in color and are streaking the dull blue sky. These clouds are known as Altostratus clouds while the dark grey clouds in the fore view are known as Nimbostratus clouds.
