Shadow elongation: Stretching or compression of the shadow shape based on the sun's angle. Sunlight travels in straight lines until it encounters an obstacle, in this case, a cloud.
The Science of Shadow Elongation: How Sunlight Path Defines Cloud Shadows
Capturing the moment when a shadow sweeps across a subject, or using the shadow itself as the primary subject, requires an understanding of light and timing. Driven by wind currents both within the cloud and in the air below, these dark shapes drift, stretch, and contort across the landscape.
The cloud body, composed of water droplets or ice crystals, blocks a significant portion of the solar radiation. The interplay of illuminated and shaded areas adds a three-dimensional quality to a two-dimensional image.

Conversely, a thick, towering cumulonimbus cloud produces a deep, sharply defined shadow with a distinct edge. Cloud drift: The primary movement caused by high-altitude winds.
