Cloud's dark base and bright edges contrast with gloomy sky background.
A close view of a middle to low angled stratocumulus cloud starts at the left and ends to the right of the sky. The bottom of the cloud has a darker shadow, and the top and endings of the cloud are much brighter. The sky is gloomy near the left corner and brighter near the left bottom corner. Towards the left bottom corner there is a tree top in the shadow creating a black tree top effect.
