The Angle of the Mild Supply
The angle at which the sunshine hits the thing drastically modifications the shadow’s look. A light-weight supply straight in entrance of the thing will create a comparatively small, well-defined shadow. Nonetheless, if the sunshine supply is at an indirect angle, the shadow will likely be elongated, probably stretching throughout the floor. Low-angle mild from the setting solar, as an example, typically creates dramatic, elongated shadows.
